If you only have a few things to sell or give away at TM6 I would like to invite you to put it on the for sale wall in the pitstop tent!
Put as much as you want on a piece of paper (A4 max) and stick it to the wall (I will provide tape). Make sure you include your phone no so people can contact you on site!
This means you won't be stuck standing behind a few bits and pieces or walking round asking if people want to buy a widget!
Obviously common sense rules apply and if anything is deemed to be inappropriate it could be removed!
