Here’s a big savings alert from our friends at Mile High on the Cheap (www.milehighonthecheap.com) in Denver. Did you know that anyone can use Costco‘s Pharmacy with no membership required. (They even called the corporate office to make sure it’s true.) You can flash your prescription to the checker at the entrance (or just tell them you’re going to the pharmacy) and you’re in. Note: Without a Costco membership, you can only use the pharmacy – no other purchases allowed. Like most warehouse stores, Costco offers excellent deals on prescription prices. They also accepts most insurance plans.
