There is a Facebook page for people on Skopelos who want to sell or are looking for something. It is called; For Sale/ Wanted in Skopelos (Αντικείμενα για πώληση/ζήτηση στη Σκόπελο)
This is the link:https://www.facebook.com/groups/105317503275084/
You have to ask to join the group and read the rules before you join.
We are sorry and were not aware of the fact that Jade Stubbs has made a similar Facebook page earlier than the one mentioned above. It is called; Buy, Swap, Sell & Give-Away (Aγοράστε, Ανταλλαγή, Πουλιέται) Skopelos.
