I just helped a Christmas tree seller friend on the corner of Mitcham Road/Charlmont Road, Tooting SW17 download a Bitcoin app so he can accept Bitcoins for his trees
He's selling 5' - 8' non-drop trees for 4.5 BTC. Come make his day
If he gets more than a few BTC sales he'll try get his wholesaler to take them as part payment on his next order.
