Diablo 3 RMAH has been available since a few days ago in Europe, there are plenty of items for sale, mostly expensive.
Good legendaries are sold for at least 7-10 euro while there are also poor quality items for 2 euro, or 1.25 euro (the minimum bid/buyout).
If you plan to sell an item for 1.25 euro (minimum), you will only receive 0.21 euro as the transaction fee is 1.00 euro and 0.04 is for the transfer fee. Applicable taxes don’t cost anything.
Selling an item for 0.21 euro might not be good business, only that there are plenty of legendary items that are having very poor stats and nobody is buying them from the gold auction house, or the prices are low, 50k – 100k gold or even less.
So the RMAH transaction fees and taxes are 1 euro for every item + a small amount, 0.4 euro for a 1.25 euro amount.
