I went to a store today planning on buying Dr. Robonik's Mean Bean Machine (which I already had) and Ecco the Dolphin for the Genesis. I decided I only want boxed Genesis games now so my duplicate purchase was because I THOUGHT I was buying a boxed game. This is what I wrote on the store's review page on Facebook.
I was very unsatisfied with their store policies. I bought two Sega Genesis games in the box with the manuals (so I thought) and when I checked out they took the cartridges out and put the boxes and manuals away after I paid them. I asked if they came with the boxes and manuals after and they said no, I said I'd rather not do the transaction then and the cashier said they can only do store credit so I said never mind then I'll just take the games. Just so everyone knows, they don't sell the boxes and they only give store credit back even if you haven't left the store.
Thanks, I just need to vent to other gamers who would maybe understand.
