under law any product that is returned to the retailer under DSR needs to be returned in AS NEW condition.
This does not need to include any seals however does need to include any documentation and cables in an AS NEW state.
The product that is returned in an AS NEW state then can be resold as a NEW product.
Any products that are returned in less than a AS NEW state can have a % charge applied therefore customer only reciving a part refund. These items would then be sold as A-Grade stock or B-Grade stock depending on the extent of damage of missing material.
Any item that is received as DOA ( Dead on Arrival ) is NOT returned under DSR but rather returned under warranty. The customer will then be sent out a replacement stock item with the faulty product being returned to the manufacturer.
Items such as motherboards and Graphic cards can be sent to a customer without a seal. This can be down to a few different reasons.
1 ) Returned AS NEW STOCK
2 ) Retail or OEM Bios update. As stock is bought by a retailer critical bios updates may be released. The retailer then will apply the bios update to the board thus breaking the seal. This product will still be sold as a NEW product.
So for me as long as everything is there... cables, books, games codes, static back or anti static packaging then im happy. If a new bios has been put on it then im even more happy knowing that I have bought a product from the retailer that is full up today and they the new bios update it covered by the Warranty of the Product.
Different story is there was something missing or if the product inside the box was dusty or dirty as that simply should not be but so what if the seal is broken as long as every is immaculate then as far as I am concerned im getting what I paid for.
