Does Anyone Know Where I Can Find Price Discrimination Data?

I want a dataset of prices where there is an increasing price for higher Consumption bands. An example could be Consumption caps in the covid pandemic panic (on toilet papers, masks or Alcohol gel). Other example could be residential energy Consumption bands, where heavy spenders are penalized, or other environmental tax is applied.

I want specifically transacional data, longitudinal per consumer, but time series panel data with average price per location that shows this higher price by higher Consumption Pattern would also be Nice.

I can find only limited/paid datasets. I would be of great help!
