This makes sense. Sales tax is not owed on re-sales of purchases on which sales tax had already been paid. So clearly this is a plot to get consumers to re-sell their products to other consumers.
Uh actually that’s not true. Sales tax is owed on used goods in most states. Have you ever bought a used car?
This isn't any sort of "plot" at all. No customer will be asked to sell or resell any product to any other customer. Each transaction is between one individual customer and B&H only. -- Henry Posner / B&H Photo-Video
So are they trying to create another ebay or what?
I think it might be closer to an Amazon Marketplace type offering. One product SKU, multiple sellers (including B&H with taxes, likely).
