Walmart has an order on line service here in Jacksonville and I thought it would be great because at the time, I was caring for my husband who was battling prostate cancer. Ordering on line and making a quick trip to the Walmart one half mile from me; would have been great. Not too much time away from my husband. Of course, as luck would have it, the two stores close to me were not taking part in this service. The closest store is 10 miles a way. What happens if I order the groceries and my car doesn't start. Won't want to pay Uber to take me there. Anyone used this service?
