Checkout

I opened my acct with Walmart with my email mrthhar@aol.com but within the last two weeks have had so many problems with your site.  Have reported multiple times that I get to check out and it gives me an error msg to return to my cart.  Have noticed many items I add to my list are not available when I add them to my cart (but I cannot check out so I guess it does not matter).  Also noticed on some flannel shirts I wanted to order, it changed the size I selected when it got to my list and cart.  Still no help or communication from Walmart to even say they are trying to correct it. If this is a problem reported multiple times, Walmart is not admitting it.
