Had to buy Maybull the 14-year old bulldog more pills. Two prescriptions for Walgreens (about $45) and one that was going to cost $109 at the vet cost only $65 at Costco. They had me fill out a form for her there, including signing a privacy statement.
The prescription said she was a canine and the drug is a dog only drug. Plus, I showed them her photo. But I would recommend that people check Costco for human drug prices, too. In Minnesota, you don't have to be a member to go to their pharamacy, but if you are you get additional discounts.
