Hello. I recently decided to return some RAM that I had just purchased from Dell as it turned out not to be compatible with the existing memory in my Alienware system. I selected carrier pick-up. I have written the return merchandise authorization number on the package, but have no idea whether I should keep the shipping label on or take it off. I also have been given no indication of when the pickup is going to occur, where I should leave the package, etc. Any help would be appreciated.
