If you or your gift recipient opens the package more than 30 days after you bought it to find ANYTHING is missing, e.g., the Blue-Ray player, you are screwed. If you can not prove it was purchased within 30 days, they will not replace what was missing even if it as cheap and easy to put in the mail as 8 screws.
That policy is buried somewhere in the fine print.
Rather, you get to buy it new from their parts department at their price. I will be lobbying the big box retailers to drop thier products.
