This is an expensive mold, yes. Nothing wrong with asking why, but there's no reason to be negative or to complain. As Jerry says, there is plenty of detail on it which ups the price. Look at the 7" ribbed ribbon tail; it's $129 for a 2 cavity. Ease up guys. If it's out of your price range, skip it. If Do-It was planning on raising prices I think they'd have started with all of the recent new molds, but those molds were right in line with the existing product line.
I don't use a ton of finesse worms, but this one looks slick. I'd be up for trying some of these out.
