[/hide] Yea...you got the wrong idea.... :wall: Great, now i have to explain it...I have used this same senario for tons of people, and they have gotten it right off the bat. Lets say you want to summon, shards are 25 each in every store. A lot of people however, buy too many and don't want to summon anymore, so they post on the forums that they are selling their shards for 21 each. Now, you want to buy shards for 21 each instead of 25, because you need 10000 of them and it'll save you a ton of cash. Now, your thinking how? Shards sell 25 each to other people too, its not like he could change the price. Heres how it works. You get: 10000 shards Seller gets: 210k 40k worth of junk P.S. the reason newb's post is wrong, is because no item is worth under its grand exchange price, otherwise, the price would dramatically drop because no one wants it and everyone wants to sell it. Junk trading is when your item is worth more than the grand exchange price, since sometimes jagex isn't the quickest to get prices fixed. For example, 3rd age armor.... Street price, people are willing to pay 70 million gp for a single kite because it's so hard to get. On the grand exchange however, its only a measly 40 million gp, so if you get a 3rd age kiteshield, start collecting or making 30 million gp worth of junk. not to sound like a jerk or anything, but in your example your seller was selling under the market value, but you said nothing is worth under its grand exchange price :P
