Best Buy Return Policy

I bought a GPS system at best buy but didn’t like it. So after 3 days I returned it in the original box with all the items in the box, with paper work and cords all wrapped in the plastic, including the receipt. The lady at the best buy refund desk said, there is a 15% restock fee for items returned, but nobody at best buy told me that! I asked how much would that be, and she said it will be $45 for you. I said, all you’re going to do is walk over and place it back on the shelf then charge me $45 of my money for restocking? She said that’s the best buy store return policy. I couldn’t believe it!!!
