Should I finance a new home theater at 0% even though I have the cash for it?
Read the fine print and you will be fine.  The big caveat is that if you miss a payment for any reason, you will be in default as far as the promotional financing is concerned and will typically owe ALL of the accrued interest, which is usually computed at 20-25% per year. Personally, I use these sorts of offers all of the time at places like Home Depot for stuff that doesn't generally need warranty service. (Wood, tools, etc) Usually I pay the thing off over time as CDs mature. If I'm buying a TV, computer, etc. I always use my AMEX, because I get an extra year of warranty service and points for free.
