I have a buy and sell shop on there...
It's pretty straightforward: you post what you want to buy, add a possible price you'd be willing to pay or items you'd want to trade and wait...
I managed to get the aries set some 2-3 weeks ago, that skin really is difficult to find, but lovely to work with!
the skin I'm wearing right now is a 'cloud skin'... It's really difficult to find for a good price, but someone suddenly sold it in the MP for 10k... which is really cheap for this skin... I spent all my FP on that, but it's so worth it... I didn't think I'd ever find it...
Oh! Oh! Big NEWS!!!! I finally found my first fairy!!!! *happy dance*
Sadly not an item I like so much, but it's still amazing!
