Here is the technique, I bought something on one of the stores (Amazon, Target, Walmart, etc) such as a Logitech mouse. When it arrives, I open the manufacture box carefully and get the mouse out, then I put something that has similar weight inside. Then I request a return with prepaid shipping label (should be free from those stores). I carefully retape the manufacture box and ship it back. If they receive the item and they see that the manufacture box is carefully taped, they won't open it to check since they do not want to destroy a brand new seal box. And the return is successful. Would this method work?
