Searching for a World of Warcraft Gold Sale

I have been learning how to play world of warcraft for the past couple of months and a really having a good time.  I started playing when a co-worker of mine offered to show me how its done.  This guy is really good!  I really have a lot to learn, especially when it comes to getting the gold that is needed to keep moving.  I have been buying the gold need, but I think it’s a little expensive.  I don’t want to quit buying it but I would like to find a World of Warcraft Gold Sale.  If I could buy it at a discounted price I would stock up.
