Yep, there is a price for one, but rarely did people buy one mount, and being the last set I didn't want to sit on 2 mounts for months. You said you couldn't afford the other 2, so I refunded you. Apologies you feel so hard done by over it.
This last batch took nearly a year to shift and I'm not prepared to invest 4 digits of own money buying batches of them to sit in stock for a year. They've taken longer and longer to sell each time, so that was the last batch from me.
Now if there is enough interest I'll happily run a group buy.
