Should I finance a new home theater at 0% even though I have the cash for it?
I bought a Thinkpad in Dec 2007 using BillMeLater, which was working with IBM/Lenovo at that time.  I was getting the notebook at the lowest price available, from the manufacturer.  I had the money to pay for it -- around $1400.  But I went ahead and took the offer from BillMeLater.  It was essentially a 12-month zero-interest credit card balance transfer loan.  Sketchy bit its very nature.  They spammed my inbox with solicitations, which was annoying.  But I set my bank to pay the monthly amount (or slightly over, since it decreases each month) and to make the final payoff -- all at the time of purchase.  This  worked just fine -- but I still had spam from BillMeLater for quite a while.  I still ran a slight risk that something would go wrong, at which point I'd face interest charges -- but I would then have paid off the item plus those interest charges.  Luckily I avoided that.  I'm not sure I'd bother doing this again, but if the sticker price was high enough, I might be tempted....
