It is an outfit (Direct xxxxxxx of Rhode Island) that wants you to give them $4,000 in return for the rights to buy lots of products at munufacturer's direct prices. They appear to be on the up and up but the upfront cost could only be recouped by a couple starting out and needing to buy lots of things.
One caution: their marketing wing will pursue you so vigorously that you will feel like you are being stalked.
