An article over at C-Net discusses the fact that many on-line retailers have strict return policies. It says that Best Buy for example has a restocking fee. That appears to be true for some items:
Restocking Fee
A 15% restocking fee will be charged on opened notebook computers, projectors, camcorders, digital cameras, radar detectors, GPS/navigation and in-car video systems. A 25% restocking fee will be charged on special order products, including appliances. These fees apply unless the item is defective or damaged, you receive the wrong item, or the fee is prohibited by law.
But the fact is that if you open it, they cannot sell it as new. If it isn’t broken, then every consumer coming after you will share in the cost of your return because the store will take a hit. Note that the fee does not apply if something is wrong with the item or you received the wrong item. They also offer extended return dates, but note that digital cameras and some other items have to be returned by January 8th. I guess the real message is don’t open it when you receive something until you are sure it is the one that you want! The fee only applies to opened merchandise at this retailer.
