It beats in store pickup for sure. I always hated standing in line at the service desk while people picked up photos or did layaways…
Home delivery always took a few days but sometimes was cheaper if you chose that option.
I think pickup tower will be good for those 1 or 2 item trips
At our local wally, they just installed the scan and go options, where they put the wireless bar code readers on your cart and you scan the items as you place them in your bag and just pay on the way out the door. It works ok, but I always had that one item that i had to get a cust service person to help with the price, etc.
They are also building a buy online and drive up to the window booth at my local wally. You don’t even have to get out of the car, they load your groceries for you. I am interested to try that out.
When I was a kid growing up in South Calif, they used to have these drive up convenience stores, where you actually pulled inside a garage type store and they would come to your window and take your order and hand it to you through the car window. Very similar to Walmart pickup minus the online aspect. Most ended up closing
