The shop.

[_Leprince]

If I'm offline:
Send me a /mail with your order and I'll see to it.

If I'm online:
Send me a /msg with your order and I'll see to it.

You can wiggle on the price a bit if you buy/sell in large quantities.
You can sell and buy at the same time. It involves more calculating, but it's doable.
