The market and the auction
Sell at a fixed price, or offer in an auction.
The camel market
You list your camel at a fixed price that you set. A 5% commission is taken from the seller.
The auction
A competitive sale for a time that you choose, from 6 to 48 hours, with an 8% commission. The coins of a bidder are held, and returned if another player bids higher.
A listed camel
It cannot breed and cannot enter a pageant until you cancel the listing.
The warehouse and Camel supplies
You sell the resources that your cars collect from the warehouse. Camel supplies sells water, fodder, tools and building materials for coins. Building materials there cost three times their sale price, so it is cheaper to collect them from the desert.
Market or auction?
The market is faster and has a lower commission, and it fits an ordinary camel. The auction fits a rare camel or one with high specifications, because bidding raises the price.
Disposal
"Disposal" sells the camel for meat at a fixed price of about 40% of her value. It is final and cannot be undone.
