How much was that total?

So we got our monthly grocery shopping done today. Last night I spent an hour or so totaling up my list and putting together the Kroger deals (they have something new this week...it worked out well for us). The total I came up with for the trip, based on the regular prices I have typed into my master list and the sales prices, was $257.23. The grand total at check-out? $220.07! I am still in a state of shock over this. I haven't had a chance to sit down with my receipt and my list to figure it out yet. But I'm definitely happy! Eric's first thought was that I must not have gotten everything on my list. I double checked it and there were a few things I did not get. I did not get a 3rd carton of 1 1/2 doz. eggs because the dates went only until mid-April. Same with one 4-pack of Yogurt. But that's it! That's only $3.68 difference, not $37! I know it seemed like there were a ton of unadvertised sales this week. I didn't realize there were that many though. I wonder if they've lowered some prices on certain items? That wouldn't seem likely with the market and the food industry the way it is right now. I feel like this a mystery that has to be solved. I'll let you know what I come up with when I'm done poring over the receipt. But in the meantime, if you have a Kroger nearby, it might be worth taking a trip there this week!
