So I just joined the 21st century and got an iPhone ;D What grocery list and grocery coupon apps do you guys use? I'm totally overwhelmed by all the app choices. I always shop at the same grocery store (Giant Food in VA) and always buy the same brand of a particular item. I don't want to visit multiple stores for the cheapest price, so I'm not looking for a price comparison app. I want to get digital coupons for the specific items I buy, specifically at Giant. TIA!
