Ok, since you asked.

...and, I see they are fishing for business here.
I placed quite a few trouble free orders with them. Spent quite a bit of money actually, over a period of time. Then, I had a big a/c project to do on my van, so I placed a large order for many a/c related tools, $$$ I get the box, and I am shorted, I mean way shorted, like one thing was in there and everything else was listed as shipped but was not in the box!. The box was sealed and did not appear to have been opened enroute, and it was too small to have ever held everything I had ordered and that was listed as shipped. I had been charged for everything including the shorted items. The box said "one of one", so there wasn't a missing box. So...I call them and immediately I'm assumed guilty until proven innocent. They can't believe it...what? You're shorted all this stuff? YES.
Now, one thing you should know, is that as far as I can tell they farm the delivery of product out to other companies....Weiss i think is one of the actual product stocking outfits they use. So, back to the phone call(s)....the ******* the phone says she will need to VERIFY the shortage by comparing the weight of the box shipped, to the weight of the items ordered. If it checks out, then fine, if not, oh well sorry, nothing can be done. Well, praise the Lord....I had been shorted some items of significant weight. It was clear to me that I would have been screwed had I not had the required proof in the form of the short weight. The shipping weight matched up perfectly with the item that was shipped, had everything been shipped it would have been much much heavier. Ok, they say, they will ship me the shorted items....so...a week or so later, I get a new shipment containing the shorted items....now....for the good part...
One year or so later....I get a threatening letter from them along with an invoice, it said that I had better pay and pay now!, Pay for what? They were billing me, a second time, for the shorted items, that I had already paid for with the original charge to my credit card! Are you kidding? So, I spent several hours on a Saturday, digging up all the receipts, correspondence, shipping info from UPS, and I looked up and documented each items shipping weight, to this I added a letter re-explaining that I had already paid for this stuff, etc....now, having better things to spend my Saturdays on, I asked them in my letter for the guy that was dunning me to verify the matter was closed, at a minimum I expected some sort of half a$$ apology.....I mean here is all the proof, all the documentation, me, the customer, has done all the leg work for you, all you have to do is read.....and what did I get. Nothing.
Right from the get go this thing should have screamed shipping error to them. The item I got originally, was the most expensive thing I ordered.... the items I was shorted, all cost less, if somebody was making up a short, would this be how they would do it?
Anyway, enough for me. If you get your stuff you'll be ok. If you don't... Godspeed.
