This post is being written for Cold's Blogging Carnival for this month. Once again, if you have not taken the opportunity to read the posts over there, you are doing yourself a dis-service.
Without further ado, on to the tips.
1. USE THE INTERNET
In his Little Green Book on poker, Phil Gordon congratulates players who want to become skilled, as they have already taken the first step, buying a book on being a better poker player. Well, the internet is your book, and I congratulate you for already taking the first step to being a goblin, reading gold making blogs. There are many fantastic Blogs, Just My Two Copper, Cold's Gold Factory and Trading With Zoxy to name a few. Make sure to read the comments as well, and do not be afraid to ask questions. In addition there are great forums for your perusal, Markco has one on JMTC and the Consortium is fantastic. The internet, and these sites are a tremendous learning tool to help you improve. Use them early and often.
2. KNOW YOUR SERVER
It cannot be underestimated how incredibly important this tip is, especially if you take the first tip to heart. Sometimes, you will read a tip that sounds so good, you hop online and immediately invest into it, only to find out it is perfectly worthless on your server. I'll give you an example, on some servers, the 2-H Agility enchant goes for 2-300+g profit. On mine it sells for a 50 gold loss. If I were to sink a bunch of money into that idea, without knowing my server, I would have been in the hole. It's also important to identify popular raid guilds and times, other AH players and farmers. Knowing your server makes all the difference between a good goblin and a wanna-be goblin.
3. Don't Fear Add Ons and Macros
At first Add Ons and Macros can be intimidating and confusing. But as Goblins say, "Time is Money Friend" and Add Ons/Macros save you oodles and oodles of time. I suggest at least a mail add on, auction mod (such as auctioneer), lil' sparky's workshop and some form of a quick auction for add ons. Additionally milling, prospecting and disenchanting macros make a world of a difference. Go to www.wowinterface.com or www.curse.com for you add ons, after doing some research first of course. Macro's can be either made by yourself, or found online in the various forums.
There you have it, 3 simple tips to make you a better goldmaker.
