I have been doing this for awhile now and i figured i would share it with you all
This may have been posted before but i did a search for it and didnt find anything.
Here we go. First what you need to do is be horde. You are going to need about 8g to start doing this. What you are going to do is go to silvermoon city and go to the enchanting supplier and buy the recipe "Formula: Large prismatic shard" Thottbot World of Warcraft: Formula: Large Prismatic Shard They sell for 6g at the vendor and you can go around and sell them for 20-30g depending on the rate for your server. I do this everyday and my auctions always sell. This week alone i have made 400g doing this. I know that may not be alot, but it is just a little something you can do on the side for a little extra coin. Oh yeah you need 8g because the auction house deposit is like 1g5s and i always like to have a few silver per character just for certain reasons.
Hope this helps you guys, Feel free to flame
