Why would they refund you in cash? Your packing slip is your receipt so you clearly didn't pay with cash for online order. Do the employees just not care?
I got only one of the guides I wanted (about 6). I didn't want to flag anyone. BB cashier was already confused that they were all rang up at $.01. I tried to avoid any extra attention. I'd never try to do what Maniac Mansion did (grabbing 50). But kudos to him!
