Oh, yes, the “sales”. I found a mattress pad on Wayfair that I was interested in, but I felt it a bit weird that it was “70% off”. I loaded the product page in the Wayback machine and found that it’s always between 50-75% off, and that the base price fluctuates by $20-40. Weird stuff.

The "sales," yes. Once we have enough price data to show how "sales" change over time, we might be able to help users plan their purchases. Some "sales" are evergreen, while some are episodic but also predictable.
