They can charge whatever they want for them because people will pay it.
There are two vendors at the local farmers market who have them, one gets $2.50 a lb, the other the same price as all of his apples. $1 a lb.
They tuck them in cold storage (our area they are picked in the beginning/middle of Sept) and pull them out whenever they need a few bucks.
I'll be the first to admit, if the $1 a lb guy is out, I may buy some of the others.
Honeycrisp, Pink Lady, and Winesaps are my favs.
