Fascinating... Whole Foods in Connecticut has both types. The organic WF brand is long and skinny and the inorganic (I know that's not the real term) is short and stubby.
My favorite is LoL half sticks which packages eight half sticks instead of four quarter pound sticks per box.
As for pricing $3.99 a pound is pretty good. Here we're looking at $5+ on average. Whole Foods inorganic is actually the best bargain on a regular basis at $3.69/pound. I usually buy LoL when it is on sale (usually two for $5 which is different from $2.50 per pound) and stock up with it in the freezer. If I need something that requires butter that has not been frozen I'll go buy some for the occasion and depending on the occasion I decide what butter I want to buy.
