Prime Pantry sounds like a Brooklyn butcher shop, but it's actually a new solution for household bulk ordering. You can fill a box with as much toilet paper, body wash, and mac 'n' cheese as your little heart desires (or up to 45 pounds worth) and it'll ship for just $5.99. There are also coupons. While we aren't sure exactly how the savings shake out, it's a great option for ordering heavy bulk items for parties. The only potential downside? It might mean the end of a few fake, Costco-membership based friendships. To wit: 50 tubs of Nutella fit in one box.
