Bad Garlic

I cook with a lot of garlic. Two of my favorite dishes use at minimum 20 cloves a piece. Therefore I usually buy it prepared. The last couple weeks prepped garlic was unavailable at the normal grocery store. Not wanting to make an extra trip to Whole Foods I got the 3-heads pack. They felt firm, looked non-moldy and of enough quantity.
Just about every clove of every head had already started to sprout. I only get about 2 descent cloves from each head. To quote a friend of mine: Rasafrasa! I've gone through three packs from different stores. Every time the heads gave no indication they were bad - almost as if this was some weird food conspiracy.
So no more. Even if it means an extra trip to WF exclusively for garlic.
