There is an unfortunate exploit I have no idea how you could work around.

Take a stack of something expensive, sell it to a vendor, then buy it again. If you have more points in discout/overcharge, it will get you coins faster.

Also, on a side note, I learned that when doing this, if you sell a stack of 95 of something with max stack of 99, if you hold mouse2 to buy it, you will get 99 of the item. The more you know.
