You can either check the price for each item manually or download an addon which puts your items for the same price as the current lowest one available.
The only thing I would say is be careful and always look good on the price before putting it up, there are so many ppl trying to bait others with putting one item for extremely low price on and insta buy it out if some1 doesnt pay attention!
Practically every time I look at materials, someone has a bait out, listed at half the going price, and some people are suckered into selling at that price.
OP, for herbs and ores, your method works fine, IF you look at the going prices and don’t list at the bait price.
I use Auctionator addon. You don’t actually need it for what you are doing, but it may save you some time.
I was putting items on the AH last night and I decided to hit the refresh and there was at least 3 to 4 people who were putting 1 item up over half the price cheaper, than what the current price was.
The item would be taken down very quickly, but that person. But I would say over 5 minutes of watching, they got maybe 2 people who put up 200+ mats for that price and they lost out on a ton of gold.
All I’ll say is those AH scammers were not from English speaking servers
When I sell mats, I always do it manually. It enables me to avoid baits, as people mentioned, and I also look at the amount of mats at a given price tag.
If let’s say, the top 4 price tags are less than 100 mats I might skip them and sell at the 5th tag where there are 1000+ mats.
I suspect that they are automating their price setting. You can probably do it with TSM. Something like “Sell 1 at 40% below the lowest price, then continuously buy all but 1 of the units that become available at that price.”
I have a herbing alt. Always put them on manually and use Oribos Exchange for the average prices over the last 4 days in EU. If the AH price is higher, I put them on at that. If it’s lower, I hang onto them and try later. The prices change so quickly for mats, it’s worth checking several times a day.
