I shop at WalMart frequently and also get my RX's there. So handy to price items, handy to order ship to WalMart instead of home for free shipping plus it is super easy to get RX refills. Mozilla comes with Amazon installed and wonder why they don't also have WalMart.
Get error message that need to use a Mozilla based browser - I am - Firefox.
This not only lets you search the Walmart website, but it also offers suggestions while you type. If you shop on Walmart, consider getting this. :)
