Stores Neglecting Old Videogame Packaging?

Thanks to GamerDad for its editorial discussing the poor condition of older console games sold by videogame stores. The writer notes: "Getting N64 games in any kind of reasonable [boxed] condition seems to be next to impossible... even more shocking is the state of their SNES and Genesis stock." He continues: "With SNES games, I can sort of understand that the deterioration of cardboard would leave you with just the cartridge and the manual eventually, but apparently the stores are now just throwing out the manual if the box is torn/useless. Even Genesis cartridges, sold in those hard shell boxes, are rarely found in their original packaging anymore. It's the systematic destruction of our gaming history." The piece concludes: "Is it really so hard to maintain a policy of keeping the product in similar condition to how it's traded in or maybe even stop accepting bare games altogether to give your customers more reason to take care of their games to retain value?" What's the solution, if any, to this problem?
