The prices drop by 100 CSC per month, I'm not sure why some are appear at a higher than normal price.

I personally don't see an issue with things be full value. There's a number of items I've bought in there that are just not for sale in the official CW shops anymore. And it's a place to sell your CWs you don't want anymore, I think that could be the point in having the CW section in the pawn shop.

That may be why you visit there, but that's not the point of the CW section. Fashion in RL has always been a market that intentionally creates artificial demand. Before there was CW shops and smaller batches, CWs didn't necessarily have resale value and there was much fear and consternation from CW makers and consumers that their items were being sold in Trades and Shops for dirt cheap prices. You had to do batches of ten, and if one set of ten sold out really fast but that was nearly all the demand for that item but you came out with another batch you could take a big hit.

I'm still not sure why this was considered a big deal, because you still got to have the item you yourself created, but apparently everyone expected Subeta to be mommy and make them Special over and above their own merits? I dunno. The Pawn Shop was meant to be a backstop safety net.

Prices in the CW Pawn Shop didn't used to drop at all. It turned out to be an encouragement for some rather substandard issues of CW items because creators who "just wanted" some item could get a certain number of backers, create the item so they could get it, and then they ate the much smaller loss of selling to the PS instead of letting the item languish around selling at distressed prices. Standards were tightened up, and prices started to be made to drop to get rid of the glut. If certain creators had a lot of glut items, you could then know not to "invest" in their stuff. Also if you were a creator and didn't want people thinking badly of your items you made more of an effort to sell them and to limit batches.

So if you get a bargain, it's because nobody beat you to it.
