So after various DE jaunts I've dusted off my GEM and bought a pack of blades at walgreens (GEM branded, stainless I believe). Love how this thing shaves. Only problem: the blades are kind of pricey. Are there any better deals to be had on blades? Are there any other brands to look for? I think I remember some people suggesting a scientific supply place's blades, but you had to buy 200 of them
