I try to make sure to give CVS some business too. I fill prescriptions there now. Also, between their Extra Bucks, the coupons they send me and their sales, its not hard to pick up a few household items or medicine that I would buy anyway. I'm not there everyday though. Prepaids at grocery stores are more $, but far more convenient for me, as CVS is out of the way, while there are 3 grocery stores I can hit after work and Walmart is not far out of the way. Depends on how much time I have.
