It is the price many people are charging (and getting) for this little item. That said, the only way to bring this obscene price down is for people to STOP buying them. (Like that’s gonna happen…).
One way is to start making use of sheitel gemachs or selling and buying used sheitlach (get over it, they wash out the cooties). When the sellers see no one is buying their overpriced product, they will be forced to lower those prices. Then people will start buying again en masse, and the whole nonsense will start all over again. We can’t win.
I have never bought myself a sheitel for over $400 (and no, I haven’t bought in a LOOOOOOOONG time). I can’t afford it. My machetenista and I shared the cost of our kallah’s sheitel, and it still came to about $800 each. Ridiculous.
