KN95 Mask Price Dataset

I’ve started putting together a dataset on KN95 mask prices after seeing masks from AliExpress being sold at a tenfold markup on European marketplaces. My goal with this project is to raise awareness about alternative marketplaces and fight price gouging.

The dataset consists of the unit prices of products advertised as KN95 masks on various online marketplaces at certain dates. Product URLs are scraped automatically, but price, quantity and availability data is gathered by MTurk workers. The data is available on GitHub and it’s updated at least once a week.
