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.
