Hello to all you grocery game users out there...I've been trying to decide whether to try this. We only have Kroger in our area that they list on the site, and I usually do my shopping at our super Wal-mart. Kroger's more expensive than Walmart, so I was just wondering...is it worth it? For example, I saw on the Walgreen's list this week that w/coupons Pringles were down to 89 cents/can for a 50% savings, but our regular price at Walmart is 88 cents/can. I'm not sure if it's worth it in my area. Thanks!!
