I use the online grocery service Walmart has now. I had to create an account and they keep my credit card number on file. At first I didn't like that, but this is so convenient for us because of our health issues. It is a safe site and I have had no problems with it to date. I had one grocery item that was missing one piece out of eight and they gave me a full refund and were very nice about doing so. I believe they do the best they can for a business and would recommend their online services to anyone. You must make up your own mind and proceed from there.
