I understand you're concern. I am picking up what you are putting down, and I promise.... I will specifically check the website before walking in, and then compare to daily active inventory.
If I was a gambling man, I would wager that what is happening here is simply a Supply Chain squeeze running into a labor squeeze.
There is no point in updating their quantities on hand on their online marketplace, as they do not sale product online anyways.... so I'm sure with their Purchasing/Inv personnel staff doing the best they can to purchase and track the product going out the door.. updating website quantities on hand per specific location is a luxury they simply do not have.
