Apologies for the tangent, but I wanted to share my review of Fresh [1]. It's a mixed-bag, pun intended.

I laughed at your mix of computer equipment and groceries, but that's exactly it: you can have a wild variety of things delivered as if they were groceries. I was most amused/bemused by the weapons selection.
