I bet it took you longer to login and write a response than it would have to check walmart.com yourself.
My local walmarts are showing $56 for a 2.5 gallon jug.
Let me educate you about Walmart my friend. You never trust their app/online. Stores a lot of times do not match app/online prices. That's why you should always go to the store and then pull up an app/online and compare. there been multiple times when app would show lower price then on the shelves and I would get it cheaper.
