What is this worth?

Paste a cargo scan, an inventory listing, a contract, or a shopping list from anywhere on this site, and get it priced against the live Jita book — then get the courier reward for moving it, because the value of the cargo is the collateral you post and the collateral is what sets the reward. Buying at the ask and selling at the bid are both shown: they are different businesses and the gap between them is the spread you would be paying.
