re: Financing a purchase via 0 interest credit cards

I'm in a different situation, but similar idea.

I got $8,000 with 21 months interest free on a credit card offer. I've taken that money and used it to prefund my IRA (I usually find the previous year's contribution only). If I time this right, I should be able to about $1500 extra dollars in my Roth account by doing this (funded my lending club account). That's better than any rewards program I have seen.

If you're slipping into the realm of financing wants because credit is cheap, that's a bad move. If you're taking advantage of stupid cheap credit to make more money, it's a good idea.

FTR: I don't intend on ever even paying transfer fees. It takes me about 3 months to put $8k on a credit card, so I can just use the last three months to transition into the next offer or pay it off if I can't find one.
