Cheryl - I usually sell my bunches of 20 for between $3.50-$5.00...but, our area is "cheap"...and I don't have them on wires anymore...the first year I did it people didn't know what to do with them, so I just dry them upside down in sleeves now! I also sometimes sell bags of just the heads...can't bear to throw things away! Since yours are wired, you might try selling them "per stem" or so many for a certain price...that works on single stem things for me!
Good luck at your market...they're fun!
