Walmart has the worst ordering system on the planet. They also pop up on searches for everything even if they don't have it. They use a system that searches for what you searched for and attempts to middle man the transaction. I ordered some commercial pole mount parking lot lights from them once that were unbelievably cheap, they showed the right part number and the right picture and the order went through. A couple weeks later I received a box of those cheap 12 volt landscape lights that you push into the ground. Ever since then I never click on any Walmart search results, it's a waste of my time.
Another thing that happened was we started getting Betty Crocker cake mixes delivered from Walmart. They were in my name and address and already paid for but not by me. This went on for over a year, a box here and two boxes there, different flavors. We don't even use cake mix. It actually took 3 calls to get them to quit leaving them here and I told them to delete all my information from their records, although I don't know if they did.
