So, here's my new plan.....
When I got home, I tracked how much each item cost and the size and brand of what I purchased.
I include this here because until fairly recently, the city I live in hasn't had a Walmart close enough to shop at on a frequent basis. Now, we have one that's a grocery store only, but considering that that's what I'm going there for, and considering this ad match policy, I can't complain. I had no idea that Walmart did this until my sister-in-law came into town and showed me the ropes. It was a very joyful thing!
If you have any desire to see my spreadsheet of prices or my monthly menu, I'm happy to share. Just let me know.
