What is their backpack policy, can you take one in? Do they hold on to it as you shop?

Per web-site: Backpacks no longer allowed This is the only store in the city requiring customers to place backpacks inside lockers located at the front of the store.

I believe that they hold your back pack. The company does it as a anti theft procedure.

I'm sorry that I don't know. I'm sure you can take one into the store. I've never had anyone check my bag when I go into the store.
