Orthodox Jewish teen Edon Pinchot just hit the mother lode ... even though he's been booted from "America's Got Talent," he's getting a bunch of free stuff!

If you didn't catch it ... 14-year-old Edon -- who wore Yarmulkes for his singing performances -- was brutally eliminated in the semi-final round.

But it's not all bad news ... The owner of Cool Kippahs -- a NJ Yarmulke store -- tells us he's a huge fan of the "Jewish Justin Bieber" ... and it doesn't hurt that Edon was already a customer. The store owner is impressed that Edon proudly sports the Jewish head piece, so he's sending the kid 3 or 4 of them ... gratis!
