I like the idea, but it would be nice to be able to sell buffs in groups instead of 1 at a time so we can give a better price for buying more then 1.
I would actually rather see something like secure trade but have it for buffs and have it so you can list your buffs and your desired price, and then people can pick which buffs they want and then put a bid in, if it is the desired price it should be automaticly accepted but if it is lower then desired price the person can accept or decline the offer on there buffs, so people can get a better price buying multiple buffs
