Some of the best prices in Las Vegas.
Whenever I am on this side of town I make sure to visit El Super. Other times I just take their ad to WalMart for price matching.
Their Wednesday produce selections are usually crazy cheap (recently there were 8lbs of oranges for a dollar, 3 lbs of Italian Squash for a $1, and even 2 lbs of green beans for $1). Thursday meat specials are hit and miss, sometimes amazing and sometimes not worth the drive. Recently pork spare ribs or beef ribs were $1 a pound, another time pork legs were $0.79 a lb.
BUT be warned. The lines here are always long. It can get dirty. And don't buy your normal (non-Hispanic) goods here, unless they are on sale, otherwise your meat and produce savings will be negated by their otherwise high prices.
