They already have, dramatically. Dan, hope yours are doing good!Good trade. I suspect the price on hornets will drop soon, but hopefully not before you get your money back!
I got 11 polyps once for 80 dollars. My LFS sells em pretty cheap too.
that said, my LFS has more hornets than necessary... and they are quite common around my area... so they might be worth more money than what they are worth at my LFS.
