I trade, sell, and buy backgrounds and emoticons for their 'turn-into gem' value to people who collect those. I will not trade you items you already own. Can I not see your inventory? That likely causes a declined trade as I cannot see if you own the item.

If you click on an emoticon or background in your inventory it will show 'This item is worth: [X] Gems'. That amount it used to determine the prices and to make it non-profit. In the table below you can find the values of the items I own. Only the combined end gem value matters. Rarity does not matter!

So for example:
You want one of my items marked as 20 gems in the table, then you can send any of the following trades for it:
- my item vs your 20 gems
- my item vs your item also worth 20 gems
- my item vs two of your items worth 10 gems
- my item vs your 10 gem item + 10 gems

This also works the other way around! Assuming you have a 20 gem item, you can request any of the following above for it.

I hope this clarifies it a bit. If not, don't shy away asking! Also, this thread receives updates, to know the latest additions just subscribe to the discussion >
