Merlin at Caboose Stop once told me a funny story..
Precision Scale once did a run of high detail custom machined wheel sets in 2 Rail O scale.. (don't recall if it was O or On3), and they were marketing them in packs of 4 axles for like $30 a pack.
So Merlin ordered "200" (thinking he was ordering 200 packs).... the lady at Precision Scale was a bit shocked but said OK.
Several months later he got a box of 50 packs of wheels and thought.. What the heck they shorted me.....
So he called Precision Scale:
Merlin: Hey you shorted me on these wheelsets.
Precision Scale: You ordered 200, I think thats what we sent.
Merlin: Yeah.. 200 Packs.. you sent 200 axles..
Precision Scale: Oh, you wanted 200 PACKS?!?..........(long pause).......
We didn't make that many. Merlin: Well, can you send me everything you have left?
Precision Scale: Yep..
