Credit Card Purchase - 'it is the bank's money no[t] yours' ?
Yes, they're referring to the credit card dispute (chargeback) process. In the case of dispute, credit card company will refund/freeze your charge so you don't have to pay until the dispute is resolved (or at all, if resolved in your favor). If the dispute is resolved in your favor, your credit card company will charge back the merchant's service provider which in turn will charge back (if it can) the merchant itself. So the one taking the most risk in this scenario is the merchant provider, this is why merchants that are high risk pay significantly higher fees or get dropped. "The statement is (in laymans terms - if not in real terms) correct. Most credit cards (I know this to be true for VISA and Mastercard) have dispute processes and will do a chargeback on the merchant - ie take the money back from the supplier in cases where you don't receive the goods or other fraud - Particularly if they can't produce a signature and (for transactions which are not face-to-face) a tracking number. Your exact rights will vary by bank, but mostly they need to follow the guidelines set by the Credit Card company - and you do need to be a bit careful - if you received goods which were fake or a dispute arises you may be up for shipping the goods back to the merchant - and you have a limited - but reasonable time - in which to make the dispute. (The statement ""the money is the banks"" is not technically true, there is no money involved until you pay it, only credit [ they are very different, but almost no-one knows that, I communicated with a Minister of Finance on the topic], but this is quite technical and as a layman not something you need to worry about here)"
"The preferred accounts are designed to hope you do one of several things: Pay one day late.  Then charge you all the deferred interest. Many people think If they put $X a month aside, then pay just before the 6 months, 12 moths or no-payment before 2014 period ends then I will be able to afford the computer, carpet, or furniture. The interest rate they will charge you if you are late will be buried in the fine print. But expect it to be very high. Pay on time, but now that you have a card with their logo on it.  So now you feel that you should buy the accessories from them. They hope that you become a long time customer. They want to make money on your next computer also. Their ""Bill Me Later"" option on that site as essentially the same as the preferred account. In the end you will have another line of credit. They will do a credit check. The impact, both positive and negative, on your credit picture is discussed in other questions.  Because two of the three options you mentioned in your question (cash, debit card) imply that you have enough cash to buy the computer today, there is no reason to get another credit card to finance the purchase. The delayed payment with the preferred account, will save you about 10 dollars (2000 * 1% interest * 0.5 years).  The choice of store might save you more money, though with Apple there are fewer places to get legitimate discounts. Here are your options: How to get the limit increased: You can ask for a temporary increase in the credit limit, or you can ask for a permanent one. Some credit cards can do this online, others require you to talk to them. If they are going to agree to this, it can be done in a few minutes. Some individuals on this site have even been able to send the check to the credit card company before completing the purchase, thus ""increasing"" their credit limit. YMMV. I have no idea if it works.  A good reason to use the existing credit card, instead of the debit card is if the credit card is a rewards card. The extra money or points can be very nice. Just make sure you pay it back before the bill is due. In fact you can send the money to the credit card company the same day the computer arrives in the mail.  Having the transaction on the credit card can also get you purchase protection, and some cards automatically extend the warranty." I have a CapitalOne credit card, and every two or three weeks, CapitalOne Bank sends me checks that can be used almost anywhere (including a deposit into my own checking account if I wish, or to pay taxes or utility bills etc)). The amount thus borrowed is counted as a balance transfer (as if I  were paying off another credit-card balance) and it will be charged 0% interest for a year.  The catch is that unless I pay off the next monthly statement in full by the due date, I will be charged interest on all new purchases from the day that they post to the account till the day they are paid off. No more grace period etc.  All this will continue until that loan amount is paid off in full.  So, I either would have to (i) pay off all the purchases made this month plus the minimum monthly payment shown on the next monthly statement and give up use of the card till that 0% balance is all repaid, or (ii) pay interest on new purchases.   It might be worth checking on the CapitalOne Credit Card site if such an offer is available to you.  If so, get a check from them, pay off the invoice using that check (actually, I would strongly recommend depositing the money in your local bank and writing them your personal check for the amount to be paid), and then pay off next month's bill in full, etc. Store cards are incredibly generous with their approvals. I recently graduated and started working making around 100k and Bank of America only approved me for a $1000 credit limit... Macys however approved me for $2000 for everyday purchases and $5000 for large-ticket items like furniture sets. It may not sound so glamorous to have a specific store card but they all allow you to build credit, and a credit card really doesn't let you do anything a debit card can't unless you're buying things you don't currently have the money for. Amazon is also issuing credit cards now, so with one of those there really isn't much you couldn't buy if you needed. If you keep going over budget with your credit card, then stop using the credit card. If you plan to pay off the card every month, then your balance should always be under whatever your budget is.  For example, if you budget to spend $500, then even though your card has a limit of $5,000 you will never carry a balance of over $500.  Most banks have an option to email and / or text message you when you pass a certain balance threshold; in this instance, you would set two notices, one when your balance exceeds $400 (warning you that you're close & need to start paying closer attention), and one when you exceed $500. Additionally, maybe you aren't ready to pay for everything with your credit card.  I prefer to use mine just for groceries, and then pay it off at the end of the month.  Whatever rewards you get for putting all of your purchases on the card are more than paid for when you cross your budget limit, costing you more in interest and fees.  Perhaps starting with just one type of purchase (groceries or gas are good choices, as most consumers are fairly consistent in their purchases of both) would allow you to ease into using the card until you get used to managing your budget with it. Personal finances are all about behavior, not knowledge.  Don't worry too much about slipping up right now and making a mistake; just keep practicing good behavior with your credit card, and soon managing your budget with it will be as natural for you as when you only used cash. I have had my card blocked at home only rarely. One occasion comes to mind - I had bought something fairly large online late at night. No sooner had I clicked Purchase than my phone rang - the bank was asking had I actually just spent [$amount] at [$online store]? I said yes and that was that. A little later I made another purchase late at night on a different card. It went through, but when I tried to use the card the next day for something small in a store, it was declined. Embarrassed, I used a different card then called the bank. They said they had put the card on hold because of the online purchase for a large amount, even though they had let the purchase go through. They hadn't called me because it was late at night, and they hadn't given themselves any reasonable mechanisms to compensate for that (like calling me the next morning, emailing me, or the like) they'd just blocked the card. We had what you might call a frank and open exchange of views on the matter.  Not all banks use the same strategies or software. I suggest: Far and away the simplest thing is just to have more than one card so that these declines are a momentary hiccup you might forget by the time you and your Rolex are out of the store. Yes it is (legal). There is of course no law requiring any business you walk in to break your money. What made you think there would be? Being a bank in the US (and in other countries) has some legal consequences, but none of them relates to 'having to do business with anyone that walks in', neither 'having to break bills for people' (not even for established customers). Yes, it was historically commonplace for most banks to do all money-breaking for free, but that does not establish any obligation to do it. Maybe the FED is required to do that, but that won't help you if you don't live near either. Cash back from credit cards is handled separately than the rest of the purchase, i.e. interest begins accumulating on that day, and likely at a higher rate, and usually comes out of a lower limit than the credit allotted to that card. Given all these differences, and the obvious revenue-generation situation for the lender, it makes sense for them to give the store an incentive, rather than penalize them further, for the use of such a feature.  Note: I am not privy to the inner-workings or agreements between large stores and credit lenders, so I cannot guarantee any of this. Most bank registers (where you write down entries) show deposits (+) to account as a CREDIT. Payments, fees, and withdrawals are DEBITs to your bank accounnt. On loans such as credit card accounts, a credit to your loan account is a payment or other reductions of the amount you owe. A charge to your account is a DEBIT to you loan account. They did this just to confuse us!
