Only good thing about self Check out at Walmart is you actually get your stuff. Amazon Fed EX drives past your house for a week with it on their truck and never deliver it. Actual true story had my package on the truck picked up a return Item and said there was no one there to deliver the package it was at my work place.
Did that with UPS. Had 2 go 2 the distribution hub to pick up package. 8 years at this address being delivered 2. They do more drive by tosses than a paperboy.
I really like the self check out one. I refuse to use them. I have actually walked out and left a cart full of groceries because that's all the check outs that were open at 10pm .
