I tried the Tetley blend from Walmart when I first got here, yuck! It's just not the same for me

. I've still got a bag and a half of Tetley that I brought back from my trip home at Christmas, should last me a while!
Super Walmart's are very handy, can pretty much get everything you want under one roof. Walmart has a bit of a bad reputation though for undercutting in some places. IIRC they own Asda too, in the UK. Huge chain.
There is a really, really funny South Park episode you should check out to get my meaning, it's called "Something Walmart This Way Comes". Hilarious parody.
Personally, I do my shopping at Walmart becuase in my tiny tiny town there isn't much other choice!
