Refunds on items still in the condition they were purchased. Labels, sealed boxes, etc, have to be in place for full refund.
Any item returned in less than premium condition will be subject to a restocking fee of no less than half(50%) of the original price.
Have you ever bought a harddrive or any type of computer electronics? How else are you going to know that it's defective? And if it is defective should I go to the manufacturer or the local store that sold it to me to get a replacement?
