Ummm...this is not a discount hobby.
If Sideshow is a little out of your range I would suggest sticking to McFarlane toys from Wal-Mart.
First off I don't go telling people what I spend on my collection, and second if any of my friends or my wife's friends think my collection is a waste of time, they can piss off. I collect for me, not to please others.
Yes from time to time a piece here or there would be nice if it was $20-$30 cheaper, but the cost is what the cost is. They have to pay for licenses, sculpting, art direction, casting, manufacturing, QC, shipping overseas, then domestic shipping.
It's a hobby that is not structured for everyone, and it's never going to be an "EVERYTHING IS 30% OFF TODAY" kind of company.
