What Should I Do?

OK here's the deal....

I just transferred 3 prescriptions to the CVS pharmacy because I had the coupons that got you a $25 giftcard, with each transfer. I just got coupons in the mail from our new Publix pharmacy offering $25 giftcards if I now transfer them to Publix. Hmmmmm.... I shop at CVS all the time, I almost feel a sense of customer loyalty to them. I even witnessed them give a free CVS gift card to a homeless man that had wandered in one day. That made me feel good about shopping there. BUT that's $75 of free groceries! What would you do? I welcome your thoughts!
