Catch me up here.

Well, I've never been on Runescape in a really long while. In fact, its right after the update when I said fuck it, I'm playing WoW.

Now I'm back just for a look around and I find it fairly intriguing. While browsing the markets, forums etc, came across a few terms I would like some elaboration on:

Street Price: I get the drift somehow, but why?

BH back some cash: lolwut?

Junk trading: Don't get it at all, go through all the trouble getting items that won't sell just to buy/sell something at street price.

 

Street Price: Seller adds junk.
BH some back: Buy for market (or junk) and BH __mills back.
Junk trading: You often make junk very fast. 400k junk an hour using some methods. Junk is often things used for powertraining such as willows, maple longbows (u), and needles (for smaller trades)
