If thinking about this question in English was challenging, consider more practice to gain fluency in formal logic. Here’s the argument presented in both languages:

English

1. If a bookstore is profitably selling below-market books, they have a discount from publishers.*
2. If they have a discount, they’re selling at high volume.**
3. If they’re selling at high volume, they either cater to the masses or have exclusive access.

Logic

1. Profits → Discount*
2. Discount → Volume**
3. Volume → Cater or Exclusive

*The only is a sufficient condition indicator.
**We’re diagramming unless here in the form that’s most convenient for the argument’s flow.

These claims form a big ol’ conditional chain, which is nice to view in both directions:

Default: Profits → Discount → Volume → Cater or Exclusive
Contrapositive: /Exclusive and /Cater → /Volume → /Discount → /Profits
