Walmart review: Website for grocery

I am a disabled veteran and I have had to shop for my groceries online and do the pickup option. In the past two years I have had minimal problems and never with the website, however lately the last few months I have been unable to shop on your website. The site is very slow and it has to reboot the site several times. The items say they cannot add at this time, then when I refresh it posts it to my cart. When pulling up my cart the items pull up in this tiny little picture I can't see them. I am using a 17" laptop screen and have superfast internet. I use to love the price of your items but with the website problems I have found myself going to Amazon and Publix for my food and other goods. Please fix this as soon as possible or fire your new website person. Thank you.
