Walmart is developing algorithmic tools to shape how it sets prices, even as US lawmakers intensify scrutiny of data-driven pricing in grocery and retail.

You might already know if you’re into clipping coupons, but a lot of manufacturers have a buy # get 1 free per 12 month deal. Taking advantage of that is often cheaper than buying whatever’s on sale for a particular month, not that you were doing that, just making a comparison.
