There should be a trend where the Bid will be about the same for most of the posts. Firstly you can bid on the lowest bids for as much gold ad you want to get rid of. Then, you can do whatever you want to do like level, PvP; log to an alt, log off, it doesn't matter. Just come back in a while, and see how many bids you won. It obviously won't be as many as you actually bid for, because people will buy them out. If that does happen, you get your gold back, so it's no biggie. Head back to the Auction House. Once again, you're able to search "Silk Cloth" without quotations and then find the lowest buy out there is. You can also post your silk that you won from the bids, back up for a margin of a few silver below the lowest buyout.
So if the lowest buyout is 1g 20s 0c, put yours up for 1g 0s 0c, or something like that, you can be more greedy if you want, but if you go to high, it might not sell, or someone might post below you, and your out of luck.
Thirdly, you must make certain that your buyout is more than you paid for the bid and you want some leeway for the amount that it costs to post up the silk or you're just losing money. If the lowest buyout is lower than your bid price, either wait, or if there is only a few really low buyouts, you can post above if you want wish.
You'll mainly make around at least 50s or more for each stack if you do it properly, at least we did.
Without a doubt, if you do this as a 70, you must be pissing broke. We just post this for the lower leveled users that need a way to get gold. It's time now for us to make it clear for you. It might not work on your server, basing on your economy and this might be common knowledge to some of you but many people don't know about it.
First thing first, you need some money to start with. 5g would be the best, it won't get you a lot but you can make some off of it and keep getting more and more till you can do the guide on a larger scale.
Secondly, you should go to the Auction House and search up "Silk Cloth" as well, without the quotations. It's obvious that there should be a ton of things but what we're looking for are any silk posts that have a low bid, only stacks of 20. You should also make sure that it's a stack of twenty and search for the lowest bids you can find.
