Doesn’t matter with commingling of inventory, you’ll get counterfeit items. I don’t buy certain items off Amazon like SD cards due to issues with counterfeit items. Also food products has issues, you’ll get items a month or two away from expiration.

If you watch all the videos on how to make money on Amazon. It involves buying liquidation items from places like TJ Maxx or other retailers selling second quality items. These items are commingled into regular inventory. The consumer ends up buying a second quality item for the “new” price.
