Is there some sort of list with all previews of items? (non-commons?)
You know, with all the item poses & stuff. C:

Sure does! :D >Menewsha Price Guide< forum has previews of all the contribution items, event items, etc.

Oh thank you very much. C:
I will use it alot!

There's also a sticky in Avatar Chat that shows all the multi-pose commons that don't display previews in the shops :)

Thank you! That's helps alot. C:
