To secure the best prices for our members, Costco.com purchases all items in bulk. Once inventory sells out, our buyers will negotiate for additional inventory. While it isn’t always possible to replenish the inventory of all items, Costco.com makes every effort to offer the best quality products at the lowest possible prices.
