I made an order in August, and picked it up after waiting 7 weeks (!) for it. They are great to talk to on the phone, but nobody made any effort to respond to emails, even with the order number in the subject line.
The official explanation was a number of the items in my large (not price, but 36 items) order were backordered. When they finally got most of them in (had arrived the day I called

) one gasket was still missing. I had to wait another 2 weeks for that to come in, but they did give me the option of having the rest of it shipped out right away. I declined because I did not want to make the trip across the border twice.
The more troubling thing is that the invoice I received in the shipment looked very different than what I had ordered, in that 1/2 dozen items were not listed, some of the parts numbers were different that what I had ordered, one set of crush washers/gaskets, were unidentified (no part number), and the total was $60 less than what I had paid through Paypal. To top it off, the box was absolutely mangled to the point where some of the smaller plastic baggies could have slipped out, and I had to spend a couple of hours trying to figure out what had happened with the pricing between me ordering and them shipping.
As far as I could tell, everything was shipped, and once I identified the "missing" items that were not included on the invoice, the price paid originally matched up.
