Grind - During the first few weeks after Classic's launch, making good money out of the Auction House alone will not be possible (items will be dirt cheap because no one will have Gold to spare). This means that you will be forced to Grind Mobs if you want to afford a mount at level 40, not to say level 60. Picking a right Grinding spot is very important, as the Gold/Hour differences between similar level spots can be huge. We will provide you with some worthwhile grinding locations in a further section of this Guide.
Check Item's Vendor Price before posting it on the Auction House - Selling items on the Auction House below their Vendor value is a common mistake. Avoid it like fire, and always make sure that you are not losing Gold on your Auctions. If you plan to sell an item on the AH for a price just a tiny bit higher than its Vendor value, you might be better off just vendoring the said item (this will allow you to avoid the risk of losing an Auction fee if your Item doesn't sell).
