really hard to find the seller or buyer for some specific rare items, because of current economy system in the game
i know there is some sites about it
but why not create a topic here?
so im looking into rulers and search similars - there is no such topic/section for trading too

RULERS OF THE THREAD:
1. no trolling
2. no price-cheks here
3. every1 can sell or buy here, european server only
4. buyers can bid on the items, sellers can choose highest offer
5. only post if you buy/sell smthing VERY RARE
6. or expensive (more than 100k gold value)
7. items for collectors(old mercenary contracts, Lire or Jaedi runes, old provision ingredients)
8.

Recommendations:
1. for your security my recommendation is not to post your @id here, but in PM to your client
2. if you post screenshot please post clickable thumbnails, like in 2nd post of this topic
3. soft for fast upload your screens - Image Uploader, for example(im usint it)

Template of the post:
- your @id(if you want)
- itemname, level, quality, starter price fpr WTS
- or your price if you WTB
- short description, if needed
- screenshot(recommended)

Example of rare items:
- ring of Cyrodiil Light vr12(not obtainable anymore)
- rune Lire and Jaedi
- Lich set vr10
- gold warlock rings(rarest weekly reward)
- expensive parts of pvp sets

P.S.
friendly topic
