Should I finance a new home theater at 0% even though I have the cash for it?
You should look at the opportunity cost for your money (i.e. what kind of return it could generate otherwise).  We took advantage of these types of offer (zero interest for x months) in the past with the goal to redirect the money to the mortgage (it was 7.5% back then) and we made sure we don't get hosed by the surprisingly high interest rate by having a big reminder in the bulletin board in the kitchen to make sure we pay off the money before the interest rate kicks in.  So we basically reduced our interest on the mortgage during that period.  Oh - we use an all-in-one account (Manulife One) so that was real nice. I would stay away from those "interest-deferred" offers - it's totally not worth it.
