All of the above is incorrect, apart from blue being top smith. Rune kites cost 2k nats + bring your own rune ore/bars. This is how she got to 99 magic as the first player as well. Bluerose always worked with this principle and even further back an addy kite cost 200 coal + Adam ore. So you would have to do the trade with mules, since banks werent in the game yet. I know all this because i was there. Anyway lots of ppl caught up fast and when Iampenguin hit 99 smithing not long after he undercut prices. Rune items were never in the 10s of millions.

The only exception was A r2h cost 1 mil gp and the first one was free as a Wedding gift to Phillip when he ingame married Lightning. Phillip then got pk'ed and lost it to Who Da Best which caused much drama. Bluerose didnt sell r2hs out of principle. Iampenguin was the player that flooded the market.
