If you have unwanted games sitting on your shelf, why not swap them for games you want to play with other UK Games Expo attendees. You can do this in a maths trade, which is run on the Boardgamegeek.com website. (link will be added when available)
On the link you will find out more information about how a no ship maths trade works. The real world exchange of games will be at the UK Games Expo. There will be a meetup at 10am on Friday, Saturday and Sunday at Hall 1 next to the Playtest Zone.
