I ordered about £1700's worth of decking, timber, fixings & screws from edecks. The delivery was about a week after the order but be aware that you may have to unload the timber from the delivery lorry by hand yourself as there was no hoist on the delivery vehicle!
My main complaint is that the quality of the timber was lower than I expected. In particular the tops of all the newel posts were split and the ends of quite a few of the decking boards had not been cut square.
I guess that you get what you pay for and in hindsight I should have ordered from a local supplier. Perhaps the most trivial but annoying issue was that I ordered 4 boxes of 200 decking screws but each contained only about 180 - a 10% shortfall.
My complaints to the company about the poor quality of the timber and the short supply of screws have gone unanswered.
