how about being able to sell 10 common a day 5 rare 3 epic 2 legendary or 1 mythical, in fact there should be a bar that tells you how much you'e sold and how much you hae left to sell. say you sell 1 common item and it takes up 10% of the bar, then you you sell a rare item and it takes up anther 20% of the bar, now you only have 70% of the bar left. common is 10% rare is 20% epic is 33% epic 50% and mythical 100%. just an idea
