It seems like everyone likes to rag on WalMart. I guess that's the American way. When someone does really well, we like to point out their imperfections. Its seems like the national sport sometimes. I shop at WalMart, mostly buying name brands (like Spam), although I also like some of their house brands (like Equate).
I am not a coffee snob, but prefer a more robust coffee, so I tended to spend more on ground coffee than I might otherwise have. I tried some WalMart store brand coffee just for the heck of it 4 or 5 months ago, and have been hooked on it. It tastes good, and gives off a nice aroma when brewing. Great Value, 100% Arabica. I am on my 4th or 5th can.
I went to WalMart to get some more as I was running out. Not on the shelves anymore, and no open spot where it would be if they were just out. Maybe they are no longer carrying it.
