Tonnes lol. I think 200, there are twelve different ones. I got them all from eBay before I joined this forum so I might try the guy in Melbourne next time
I bought some lithop seeds from one seller which I am positive are dodgy, there was supposed to be 50 and there ended up being about 120 so I don't know if they were smashed
I sowed them anyway but there has been no sign of life and it has been about a month.
But the ones from the other seller are going better than I expected, I just can't keep them warm all the time with the erratic weather here.
