I have 16 left I think. $35 each plus shipping or 9 shipped in a flat rate box for $280 I can fit 9 in the medium flat-rate box but I have to cut the top flappy piece off the packaging to get 'em in there. I haven't tried, but I could probly fit a smaller number of them in a small flat-rate box if I took 'em out of the packaging. I'm happy to do this if someone wants a lesser number.
