Should I finance a new home theater at 0% even though I have the cash for it?
I have abused 0% interest programs time and time again, but only because my wife and I are assiduous about paying our bills on time. We've mostly taken advantage of it with bigger purchases that we've done through Lowe's or Home Depot (eg - washing machines, carpeting, stove, fridge), but its been well worth it.  There are two rules that we set for ourselves whenever we do a 0% interest program -- 1) We have the money already in savings so that we can easily pay it off at any time 2) We agree to pay our monthly bill on time There's nothing quite like using another person's money to buy your things, while keeping your money to gain interest in a savings account.
