People always complain about variants being released as PBandai. I know a bunch of store owners, and they all say the same thing. PBandai is the best choice as sometimes the kits just don't sell. Last year, we got a bunch of the GM variants and frankly they're not all popular. No one wants to have stock just sitting on their shelves. Just because YOU like the kit doesn't mean that everyone does. At least with PBandai, stores can do an inventory beforehand to avoid this.
As for the price, stop buying them from American sellers. They charge the cost of shipping, plus money to actually make money. Pay attention to new kit releases and order from Taobao, Gentei kits, etc. You'll pay the cost of shipping plus like 10 bucks for the stores profit.
Or better yet, make a friend overseas. If i ever really want a kit, i have my friend pick it up for me.
