I've been using this for a few weeks now, basically a more affordable version of Peapod.

$4.2B valuation for a service supermarkets already offer? Am I missing something here?

I use Cornershop here in Mexico (Monterrey), it works like a charm and with the scheduling of order time one can get the groceries delivered just after arriving home from work or similar. We use it once or twice a month and once a month we go by the store for good old times sake.
I have tried using Instacart several times but I dont think this app has solved grocery delivery completely. I don't like the fact that the mark ups they have are hidden. How would I know how much extra I am paying than the store? I want to see my receipt and get an idea how much extra I am paying
