In the end the MOD aka Manager on Duty located a six pack of smart water for me. If I had not pushed the issue with the associate(s) signed to self check I would have left the store without making my water purchase. Three different self check associates told me that they could NOT ring up six single bottles of smart water as a six pack of smart water. If the product in the six pack is the same as the single item product, why wouldn't you sell 6 single bottles to the custoner as a six pack? I even took a picture of the shelf label which included the bar code and the price. In fact after two floor associates said they weren't familiar with the item as a 6 pack, I used Walmarts app to look up the item. The item was in stock. It said it was ready for pick up today at the Duarte store. If I had not used the app I definitely would not have been able to purchase the water. The MOD said the inventory was listed as -2. I said, It's listed as in-stock for me. I was even able to add it to my cart."Everybody knows an OOS item cannot be added to a cart or purchased online or in-store. Basically that is the purpose of the OOS function. You can't sell what you don't have. If OOS items could be purchased, inventory counts would be a mess. The system would essentially shut itself down over time. Zero counts (which are necessary to ensure stores are properly replenished) would be incorrect and create real havoc from the DC to the store and everything in between. The MODs numbers should have been the same numbers that showed the item in stock in the walmart app. Her supposed -2 should have prevented me from adding the item to my cart. It didn't which leads me to believe that she was giving false/incorrect information to get rid of me. As soon as I showed the MOD the item was in my cart, she said to give her a minute. In all honesty I assumed she would come back empty handed. My assumption was incorrect. The MOD back peddled and did the right thing in the end. I respect that enough to give 3 stars.
