Trade with friends

Super cell can you make this possible
To trade items using the roadside shop with neighborhood and Game Center friends
Several time my items have been purchase by other Game Center friends and not by the player I agree to help

Thank you

If there is a way on how to trade can you please make me aware of that

If u trade with neighbors tell them u are posting and put it in the last stall. If trading with friends/followers I usually buy something from them and they know to come to my farm for what they need. Sometimes they aren't on line and miss it. That's the chance you take. Good luck.
