Following up on my last post in a NESS thread, I recently had a much better experience with them. Ordered some valves, a shirt, and a pirate flag (never have to guess which float is mine) and as usual bit the bullet on overpriced shipping...for $15 per 3500psi freshly rebuilt 7/8" DIN valves, I'll put up with a good bit of shipping charges. 10 minutes after ordering I get a call from John letting me know the valves are out of stock and the shipping was higher than it should have been regardless, and asking what I'd like to do. I said scratch the valves and ship me the rest at whatever USPS flat rate priority container was cheapest. They said no problem, and we'll call you when we get more valves in.
That was Tuesday am Hawaii time; my order was just delivered today. After the refund for the out of stock items and the shipping overage, total shipping cost was about $6.
Since I'm too lazy to go find my last post, I'll say that the last experience was not bad, just overpriced shipping and deletion/refund of an out of stock (I assume) item without communication leading me to assume it was a shipping overage refund and instead I opened the box to find no nifty t-shirt. OTOH, the AL40 I ordered from them was in great shape, dirt cheap, freshly O2 cleaned/hydro/vized, which is why I ordered in the first place. YMMV, but I've liked them so far.
