Enact a new rule, “Flea Market”:-

A Seller may take a Good to the Flea Market by reducing their own profit by £2 and posting a blog entry with the title “Flea Market:” followed by the name of the Good, or a string similar to its name. This is known as a Flea Market post. A Seller may not make a Flea Market post if they already have one to which the Broker has not responded.

The Broker may respond to a Flea Market post specifying an Offer in Pounds that he is willing to give for the Good. This is equal to the Market Price of the Good divided by 100, then multiplied by a random number between 25 and 175 (generated without using the GNDT, and rounding down), then reduced by 5 (to a minimum of zero).

Within 24 hours of an Offer being posted on an Flea Market post, the Seller who made the post may remove the relevant Good from their possession to gain a number of Pounds equal to the Offer.
