If you are purchasing anything from Best Buy, be aware of their restocking fees and return policies.
Here are the relevant entries:
14-day return period
We accept returns or exchanges 14 days from the original purchase on computers, monitors, notebook computers, projectors, camcorders, digital cameras, radar detectors and video games purchased as used.
A restocking fee of 15% will be charged on opened notebook computers, projectors, camcorders, digital cameras, radar detectors, GPS/navigation and in-car video systems unless defective or prohibited by law. A restocking fee of 25% will be charged on Special Order Products, including appliances unless defective or prohibited by law.
Refund will be in the same form as original purchase. Exceptions: Cash, debit or check purchases over $250 will be refunded in the form of a mail check within 10 business days of return.
Restocking fees aren't uncommon at comparable companies. Sears, Target, and Circuit City, for example, all charge 15% restocking fees for products in certain categories.
Needless to say, it's advisable to inquire about the particulars before purchasing products that may have to be returned.
