My son was the unlucky shopper at Best Buy who bought a game system in a sealed box only to find upon opening it that there was an old system in the box. Someone had obviously bought a new system, put their old one in the box, and returned it to the store for a refund, thereby getting a free replacement. When DS went back, they accused him of being the one who did it, refused to give him a refund or new game system, and only relented because he wouldn't leave and got louder and louder. Before he left the store, he made the customer service representative open the box in front of him to be sure there was actually a new system inside. Now, I refuse to shop at Best Buy, but I also open boxes either in the store or in the parking lot to avoid any problems.
