Haven't read the whole thread completely so sorry if this repeats. One problem that can't be addressed by any site is that stores within a few miles of each other don't have the same price on the same items. I am within driving distance of 3 Walmarts and they all have different prices; the same with Foodlion and other stores. So even if a regional price is listed it doesn't mean the store close to you will follow the exact price. I have had it explained to me that they adjust their prices according to the local competition. So if there isn't much near one Walmart their prices might be higher on some items. It is also why they won't price match among their own stores. My husband's job involves grocery stores so I am in and out of a lot of different ones and the prices don't hold constant even as much as 2 miles away sometimes. I was shopping in a store he was working in a few weeks ago and he got a call and had to go to a store a few miles away. So, I just decided to buy the items I was planning to buy at the other store. It didn't work out, they were higher on the same items. The other store had adjusted the price down because of a store near them. So it is impossible to make the prices fit every store even in one town let alone the entire region. This might explain at least some of your different price findings.
