With Publish 80 comes a change to vendor fees. You can no longer charge just 499 gold for an item and not incur any additional vendor fees. The pro-rate change closes that loophole. Some may say it is for the better...others for the worse...I myself have mixed feelings. I had many items that were well over the value of 499 gold that I would sell on my vendors for 499 gold just because if it sat I would not incur any vendor fees. Of course those bargains usually never sat long. This is just an FYI.
