Walmart is such a big buyer that it already can do pretty much whatever it wants with it’s vendors. Big buyers with clout have onerous rules, and the infraction of said rules causes chargebacks (fines against the cost of the merchandise). So they not only strike a favorable deal based on volume, but can incrementally lower the price all sorts of ways.
yeah, i’d just want to sell them the stuff outright, and let walmart worry about it from there
