From the title to the price: what Chux asks for, how the category decides the rest, and what appears in the grid.
| Mode | Meaning | How it sorts |
|---|---|---|
| Fixed | The amount you are asking | By the amount |
| Negotiable | You have a figure but will talk | By the amount when there is one, last when there is not |
| Free | You are giving it away | As zero, so always the cheapest |
| Exchange | For another thing | No number, sorts last |
A card carries four things: the cover, two lines of title, the price with the town, and one attribute. Everything else (the description, the other photographs, the contact) waits until the listing is opened.
