If you're talking about the small blocks of cheese (random weight, sealed in plastic) then Win Co Foods has some good sharp cheddar back by the deli area. It's like $3.19/pound.I wish I could find a few blocks of Farmer's cheese. Crest you to sell an off brand that was pretty good.
I pick up a block about a pound or so and it's good to me especially for the price.
(Costs more for sliced.)
