Walmart is no longer a great place for values.  They have increased their margins to the point where there is no reason to shop there especially for groceries where they are more expensive than several other local grocery stores.  Mr. Walton would not approve!

I do a lot of comparison shopping.  Walmart grocery prices are high except on "specials".  Aldi has the lowest prices in our area.  Walmarts low price guarantee is a joke.  Most prices are not advertised and few people will bother to present other ads and request the lower prices.
