The name sounds good, but I reckon it would be hard to monetise. Maybe if you could get a feed (no pun intended) from the online grocers so people could find the cheapest price on a certain foods, then pick up a commission if they go ahead with a purchase...?
A worthwhile hand reg, not sure how much I'd pay in the aftermarket though. I'd hang onto it for a few more years until online grocery shopping gets bigger.
