If you've got an item you'd like to use for barter in a post-Brexit UK please suggest it here. We'll put it into our complex algorithm which will calculate its Brexchange rate against the other barter items currently listed. You can see a full list of currently algorithmised items here.
We need to work together to ensure we can bring some sort of order to the chaos that will no doubt ensue after Brexit. Leaving the EU will likely be the closest event to a Zombie apocolypse that any of us will experience during our lifetimes. It is our duty to protect future generations in the UK and make sure the new barter system that will be required is fair, documented and transparent... although we won't be sharing our algorithm.
