Coupons.com has purchased Grocery IQ, an iPhone application that allows consumers to create and share shopping lists by adding items from a catalogue of over 130,000 name-brand products found in the grocery store. Coupons.com will use that technology to distribute offers on the selected items, which consumers can redeem by showing their cashier, crediting them to a supermarket loyalty account or printing them out.
