Well you could argue that it wouldn't be Walmart that does it, it would be the producer so Samsung, Apple, LG, Asus, Acer etc would sell their products with a digital twin (NFT) which provides sales from future purchases.

That being said, it could reduce the need for new products/versions being created every other week. However, there would need to be a somewhat centralized 'marketplace' that facilities the second hand sales which is where Walmart could step in with some perks for selling with them.
