I agree, the main issue in this case was that their current ordering system (which by deficiency or design allows for ordering beyond set quotas for products) didn’t interact well at all with a promotion for limited items that couldn’t be replenished after the fact. I reckon their sales team may not have foreseen the fallout from what seemed like a good idea on paper, though it’s not like this is a new problem…just a new manifestation of an old one.
