There usually is a limit of one per customer on small batches…they still sell out quickly. Normally, on a really anticipated item, they sell out in hours, if that long. It’s not unusual for all the items to be “in carts” within fifteen minutes of being listed in the store. Then it’s a waiting game to try to snatch up the ones that “fall out” of carts after 45 minutes. As long as the notice all in carts, there’s a chance one will become available. Good luck.
