If I had banned myself from walmart, I think I would have easily saved myself several hundred quid. It's just SO CHEAP. Agree with Quentin tho, the portion sizes with the food are vast, and I'd quite often just eat an appetiser for my main and it'd be dirt cheap. (So would make up for it with Fishbowl Margaritas). Quite often we ended up at places during happy hour, premixed drinks, some cocktails, local moonshine, beer etc usually come in at a good price, but if you are a wine drinker or like a specific spirit, then you might get your shirt pulled off a bit - JD & Coke being a good example, so you're prob better off getting your liquor at duty free and just buying mixers when you're there.
