I like the dash button, but for the hackable nature of being able to use it to command things via IFTTT. The Dash Smart Shelf, however, does not do that… it locks you into reorders of items that are pricier than just going down to the store and buying yourself. Or going online and choosing a different vendor when one gets overpriced. If you’re looking to save money (and we usually are), buying an device to autoreplenish at whatever price… is simply not wise.

Meet Amazon Dash Smart Shelf – Our auto-replenishment scale senses the weight of everyday items and places a reorder or notifies you when you’re running low.
