I was looking through the wedding classifieds and came across a listing titled:
FS Updated (PIP): boxes, crystals, hair comb, HM t-shirts, Iron on letters, round 1" labels, and a Short White Dress
and there is a rhinestone comb in there for $20, not sure if its your style, but worth checking out! I'll post the link but I don't think it'll take you directly to the listing, so just look for that heading, I think it's on the second page.
