This is an economics question. I've been asked to describe the pricing strategies Peloton uses. I know that it uses a form of 3rd degree price discrimination globally (charging different prices in different regions). However, I don't know how to describe its use of subscription tiers. They charge more for tiers that give the customer more access while the companies costs don't change much at each tier. Is this a form of price discrimination or a completely different pricing strategy such as two-part pricing, etc.?
