Not all exclusives go up in price, some can be found for under retail on the regular. The Shinkengers are an exception though because of the shows popularity. They are not typical of exclusives or sentai figuarts in general :lol

Stuff like Gaoh and Yuuki however have eluded me for ages because they've gone up in value.

This. I mean, I used to be right there with those people who'd bitch, but after awhile that burns you out. It sucks, but we have Middlemen. Especially with ST who is a total bro and lets you pay as you go instead of paying upfront like others, there is nothing to complain about.

Outside Kuuga Growing, it's seems to be the norm for exclusives to raise in price.

Sure but :

New Den-O Strike Form (Original)
Sieg Imagin
Neotrooper
Zectrooper (Shadow)
Bladeblade
Gills Raider
CycloneClyone/JokerJoker
Kivaarrow
CycloneAccel Xtreme
Guard Chaser
Faiz Axel
Ridevendor
G Den-O
Birth CLAWS
Burakawani OOO

And a host of other exclusives regularly sell for retail or below :p None of these have appreciated. So to be fair for the most part, barring things like Yuuki Gaoh Rising Ultimate and a few others, the prices don't go too crazy high.

Yeah, I was just saying in general. I've looked around at all the prices and am well aware of the price hikes/drops. Gokai Pink/Yellow jumping price right at release was kind of surprising, but not really given the popularity of Gokaiger.

I'm just going for the Red Rangers from my favorite series. I don't have the money to pay 100 dollars for exclusives, and if I did, I'd rather buy the Robot Chogokins.
