Hi everyone!
One very handy-dandy thing that Wash U has is Bear Bucks. Bear Bucks is a cashless system on your WashU ID, and you can swipe your ID to make purchases with Bear Bucks both on and off campus. Some stores even give Wash U students a discount when they use Bear Bucks instead of a credit/debit card, and Wash U also gets a small percentage of sales associated with Bear Bucks to cover administrative costs for the system.
