+2 I bought quite a load of 3-pc valves, camlocks, street elbows and silicone tubing from them, and wanted to include some Type A camlocks that were not in stock. I included a note asking them to reserve me the Type As, and the next day they sent me email and left a message on my answering machine that the Type As had just come in and if I ordered them they'd deduct the separate shipping charge (note: their shipping charges are the lowest I've encountered to begin with!).
Very pro-active outfit that I'll definitely use whenever I need what they're selling...
Cheers!
