Should I finance a new home theater at 0% even though I have the cash for it?
I think so.  I am doing this with our furniture.  It doesn't cost me any more money to pay right now than it will to pay over the course of 3 years, and I can earn interest on the money I didn't spend. But know this: they aren't offering 0%, they are deferring interest for 3 years.  If you pay it off before then great, if you don't you will owe all the accumulated interest. The key with these is that you always pay it, and on time.  Miss a payment and you get hosed.  If you don't pay on time you will owe the interest that is being deferred.  They will also be financing this through a third party (like a major bank) and that company is now "doing business with you" which means in the US they can call you and solicit new services.  I am willing to deal with those trade offs though, plus, as you say, you can always pay it off. WHY THEY DO IT (what is in it for them...) A friend of mine works for a major bank that often finances these deals here is how they work. Basically, banks do this to generate leads for their divisions that do cold calls.  If you are a high credit, high income customer you go to a classic bank and request cash, if you are building credit or have bad credit, you go to a "financial services" branch.  If you tend to finance things like cars and furniture, you get more cold calls.
