As JohninKS pointed out, it won't make any difference to folks who have copay on their insurance unless they, and the pharmacy, pay attention. We use the only locally-owned and operated pharmacy in our valley and they still deliver for no extra charge. They don't charge us the copay if the drug is cheaper than that. Even though it may cost us a bit mroe in the long run (it'd be cheaper to buy mega-quantities through the insurance mail-in) we like patronising them and the personal service/attention. So, WalMart? NO!
