I'm not sure if this is the right place for it, but I thought it's the most likely. :o

Well, I have decided to collect old items and especially crafting mats that are not available anymore. I have quite a lot of them already and would be open to trade for other "collecibles".

My current most wanted item is Questionite Bindings. If you have some left from before the On Alert patch, I would buy them for 100 G each!

Um, why? It's not like this item is going to become VALUABLE. Unlike old, unavailable costume unlocks.

Not so much as them being valueable, its that they are no longer gettable, and its kinda like an nice just to have some old stuff that no one uses anymore but rlly no longer exist.
