I just applied for an REI credit card. It gives me 5% back on anything I buy at REI (in addition to the 10% membership dividend I get on full-price purchases), plus 1% back on anything else I buy. My 2011 dividend was $97 on almost $1000 of full-price purchases, and without running any reports yet I would guess I spend at least another $500 or more on sale items; the extra 5% credit card reward for that would have been $75. And if I had put even half of my budgeted spending on an REI card I'd have received another $300 back, for a grand total of $475. Incredible!. Granted, the dividend payment with any extras can't be cashed out until July 1st, although up until that time you can spend it at REI, but being the kind of woman I am I spend a fair amount there every year, and if I don't need stuff I'd still have the cash come July.
Anyhow, it's hard to say what interest rate they'll charge me, but it's a no-fee card, so that really doesn't matter so long as I use it for budgeted expenses. Only a few months ago I'd never have trusted myself with this, but although I'm hardly the most aggressive at debt payoff or accelerating my savings in a huge way, I have lived within my means for a year now by spending according to category balances, even if that meant adjusting the budget. So who cares if it's on a credit card? The only difference is that I'll have to make sure I pay on time, and with YNAB that ought not be a difficult task!
