Fairway sells two "european style" butters labeled "Plugra" and manufactured by Keller's; (1) half pound in a silver foil wrapper and (2)one pound in a red and white wax wrapper. Both are priced the same. I've been buying the red label for quite some time, but I can't figure out why the red label is half the price. It tastes great -- like the butter served at quality restaurants -- and only costs a little more than regular Land O' Lakes butter. Anyone know what's going on?
