Have you tried talking to the department manager of HBA(health and bueaty aids) at Walmart? They are usually there in the morning on weekdays, if not ask to speak with a member of management. Perhaps they can order more or hold some aside for you perhaps? When the next shipment comes in. All items in a Walmart store work on a POS(point of sale) replenishment system, meaning when it sells at the register, it automatically orders another one. That's what's happening when you hear that beep, besides ringing you up. And if the shelf space for that item is say 4 in total..then it all depends when the last one was sold, as to when you'll see another on the shelf, and if someone one day say, buys all 4? Then it may be "out of stock" till another truck comes from the warehouse. But even inside this system, they can usually order more of an item. ESPECIALLY if it's a customer request. So again I'd suggest telling your story to the dept. Manager, or call the store manager directly.
Buy in bulk
Have you tried ordering from the company directly
Not sure about why but looks like out of stock most places. Amazon has it in 2 or 6 packs showing back in stock on April 16th. I'd order and have it delivered, keep you away from the People of Walmart! Haha
