Target also has a $4 list but it is about the same as the Walmart list. Walgreens just started a subscription type program. Apparently you pay a price to join and then you get a really long, inclusive list of drugs that MD can write RX for but should be for 3 months - the best price is $12.99 for 3 months of drugs. Not sure what the joining price is - something in the back of my mind says $100.
