Canceling credit cards - insurance rate increase?
You don't need to have a bunch of credit cards lying around; just a couple is fine. Get a "rewards" card (without annual fee) that pays you back for use, and use it regularly to buy groceries, for example. Pay it off promptly each month, using the rewards, if you like, to reduce the amount you have to send in. Or you can use the rewards for other purchases; some merchants offer $25 worth of merchandise for $20 in rewards. It used to be the case that you could negotiate a discount for paying cash rather than use a credit card, but that is a lot harder to do now, in many cases because credit-card company contracts with merchants prohibit this practice. Also, merchants often prefer credit cards rather than cash because money-handling is an issue (pay for an armored car to come pick up the day's receipts, or risk getting mugged on the way to the bank, possible burglaries if you leave the money overnight in the store, daily balancing of cash-register trays, etc.) So, not being in debt and being rich enough to not need to be in debt are laudable goals, and you have my best wishes that you will reach them soon, but getting rid of all your credit cards as a part of not being in debt may be more trouble than it is worth. Keep a couple, pay them off promptly, and if you are concerned about being in debt, you can time your charges so that you are in debt at  most 2 or 3 days each month.
