DH and I use our credit cards for most purchases, paying them off in full each month.  Right now we have a Citi card that gives cash back, but maxes out at $300 per year.  So I went looking and found that one credit union I belong to has a reward card.  I switched over my regular card with them (that I never use but keep to maintain an 'active' account) to their reward card.  Now, when we reach the $300 limit on the first card we can switch to this card and bring in a little bit more each year!
