I wanted to update the exchange article for the Dragonbone Upgrade kit.
The exchange buying limit per 4 hours is 2, just like many treasure trail items and spirit shields, torva, etc.
I didnt see an option to edit that article so i thought id post it here.
I found this out because i had an offer in for 5 of the kits in the grand exchange, i got 2 of them,( i had the offer in for 25m each) and i got them for about 22m.
Even 30 minutes after i got the first 2 kits, no more were buying, so I got a friend to purchase 2 of them for me ( for the same cost of 25m each), and he got 2 of them instantly and had a few mil leftover. Then i aborted my G.E. offer for 5 dragonbone kits and changed it to 1 kit, and about 4 hours from when i bought the first 2 kits, i got the 5th kit, again with a few mil leftover.
