Item Pickup Today Does Not Mean in Stock at Walmart

Obviously, I assumed too much when seeing this meter stick on Sure, it’s available for pickup at the Pearl City location today if I order/buy it online. So I guessed that for the item to be available today, it should be in stock at the store. Otherwise, how can it guarantee the item be ready for pickup?

Well, of course, the item is NOT in stock at the Pearl City location. I asked the clerk who checked inventory and said they are indeed out of stock. Thanks Walmart. But I did find a tape measure with metric markings at a close enough price.
