The Sorting Reset: An Economist's Guide to Why Nobody Pays the Same Price
$9.99
Book 17 in T. Rose's Qualogic Learning Reset series — a 12-page economist's guide to noticing when you're being charged a different price than the person next to you.
This guide covers price discrimination — the three classic degrees of it, and how coupons, personal data, and pricing algorithms make your own price more personalized than you think.
Inside, you'll learn:
- The three classic degrees of price discrimination
- Why coupons and discounts function as self-selection filters
- How to read and counter your own personalized price — grounded in a 2025 field test finding ~75% of grocery items on a major delivery app priced differently across shoppers, with gaps up to 23% for identical products
Includes the 7-Day Sorting Reset action plan. Instant PDF download, 12 pages.
