I don't think that's going to serve the function you think it's going to serve.
One of the first "market" things new players learn is that certain items can be bought for less than their store price, and then sold at the store. Lvl 50 Recipes and jank salvage were how I started to become the man I am today - following TopDoc and Fulmens around, gathering up whatever Inf falls out of their pockets.
If you scoop all that 'junk' off the market, you're actually - unintentionally, mind you! - robbing other just-starting-out Marketeers of a profitable niche - that isn't profitable enough for them to have a richer player choke them out.
Just my thoughts.
There are plenty of such items with under 10,000 for sale, ThatGuyThere.
My guess, Ranger, is that for most items with 10,000 for sale you will get to a certain point (maybe 6000, maybe 2000) where all the remaining items are considerably more expensive. This is because, at some point many would-be marketeers try making an artificial shortage of common salvage. They keep buying at 250 and selling at 10,000 - buying more and more- until they run out of market slots. There are a few types of salvage with high enough demand, like Alchemical Silver, that you can keep juggling; for the rest, you'll often see two or three thousand abandoned for-sale items. (I've seen someone give up an attempt in realtime; one day there were 3000 bids and the minimum price was 50-odd thousand, the next day there were 1200 bids and the minimum price was 20-odd thousand. The items sold, one or two double-XP weekends later. )

So you think you're a hero, huh.

Hello all, I have decided to start a market purge of the items that have over 10000 on the market. Here is the way that I will do this by bidding on items at their store price. Doing this means no risk of lose. Anyone want to join in can.
