Guides and data

Buying a used or discounted appliance is a data problem: what the categories mean, what a unit should cost, how long it will last, and which seller to trust. These guides answer those questions with named sources and our own national store data. No affiliate links; the only commercial relationship on this site is disclosed inside the one comparison where it appears and on the about page.

Start here: what each term means defines the categories. How to verify a store is the checklist we apply to every listing. Prices by type and region carries the pricing formula.
