I have an iris sale every year in July through August. I post it on Craig's List and charge $3. each for most, with a few of the newer ones higher. I also have a grab bag that is 20 irises for $30. Many people take advantage of that, and of course they get many more then 20 in the bag, so they are really tickled when they pick them up. Many of the people who buy them come back the next year during bloom season to see them all in bloom. That of course gets them to fall in love with some more, and then they often make an order for some. This last summer when I dug up a large bed, I offered boxes of irises on here to people for postage, my choice of cultivars, and I had more takers then irises. Which was great, because I didn't have to compost them.
Cross Examined was a bonus that I didn't really like much. So it went.
