I have 2 greater pet dyes.
I will trade 1 greater dye for 2 lesser dyes.
or 150 diamonds for each greater dye.

hey there~ I'm willing to trade both your greater dyes for 4 lesser ones ^^
if it's fine, ping me and I'll send them over.

Ok, yes. Do I just post it on trades? Or what do I need to do?

well, such trades are based on trust here. ^^

both players send the items they're trading to each other (using this ** function in their inventory), with a CoD of 0 (or 1, so the person will not accept the trade automatically with say mission satchel trades).

it's considered polite that the one who sends items first, gets to accept the trade first (so it doesn't look like the other person just accepted the trade and didn't send anything back).

so it would be like this:

1. I send you 4 Lesser Dyes (no CoD).
2. you send me 2 Greater Dyes.
3. I accept your trade.
4. you see a notification that I did it and then you accept mine.

though I don't care about such formalities, just don't forget to send the dyes to me. ^^
I sent mine already.~

ok i will send them.

I accepted your trade~ did you get mine though?
if there's anything wrong, I can return your GPD immediately. ^^

nope, I got it! ;^) pleasure doing business with you!
