How to Use the Snatch Tool

You can’t ungold cap someone. You can make their profits smaller and take away market appeal, but you will be hard pressed to battle someone on the auction house and cause them to lose gold. There are ways to compete with opponents but you won’t be blowing them out of the water the way you can in the real world. This is largely due to the lack of quality disparity among goods. Since you can’t make a better product, all you can do is change the price, quantity, and time of posting.
There is a strategy however which allows you to compete with your auction house brethren and push markets into more profitable ranges. What you do is run a normal auction house scan with auctioneer (use the little blue double arrow for a fast scan) and then go into searches (right click the yellow magnifying glass) and select snatch. Within the snatch tool you can set values which you’d like to buy items for (remember they are based on individual item prices) and then click search to see if any items were found within your purchase range from the previous auctioneer scan.
Keep in mind that you must have something to search in order for scan to work. You cannot run snatch without performing a scan first and every snatch search until the next scan will rely on this old information.
Example:
Step 1: Run a fast scan.

Step 2: Set saronite ore to 85 silver (17 gold a stack) and hit snatch.

Step 3: If saronite appears for bid or buyout at 85 silver or less than it will appear on the snatch screen.

Step 4: Select purchase for each and confirm your decisions.

Step 5: Go to the mail and collect your items (if you bought anything out)

Step 6: Prospect your saronite or make some bars for transmutes or w/e you want to use it for!
It’s that easy!
One more tip, once you add an item to snatch it stays there every time you log on and you will need to change the values if market prices change.
