I was joking, but at the same time serious.

He's inferring that sometimes, err, most of the time, it seems that puddington will accept a price suggestion based on what their sales alone are. One time she said she sold like 20 buds for 16 keys, thus allowing them to accept the suggestion to increase them to 16 keys. I think it was 16 keys, don't quote me on the specific numbers, but that's what had happened.

The reason he's saying you'd have to wait until Puddington sells is because then she'd have to lower her price if this gets accepted, resulting in capital loss on this item alone. If it doesn't get accepted, she'll have a better chance at selling it.
