I thought it was a website issue, but now wonder if it may relate to Firefox or my Add-ons. I was able to select items and edit my "cart" on walmart.com, but when I clicked "Purchase Now" got re-cycled back to the order page. I contacted walmart online and they suggested I try another browser. Sure enough, when I used Safari, all went well and my order was placed. This has happened with other websites occasionally, but not with major sites like Amazon or iTunes. Any assistance or suggestions greatly appreciated. I am an old grandpa who appreciates, but has no computer savvy. Thank you.
