A quick quide for you all, I've used this a fair few times while flipping items and made around 30m from doing this but I don't enjoy doing it as it's pretty tedious and don't plan on doing it anymore so I thought I'd share. When you need to do is go to is go to Oziach's Armour in Edgeville (it's the guy who you finish Dragon Slayer on) and buy all the Anti-dragon shield's you can get as they cost 26gp each (obviously this increases with the more you buy). Then you run back to Edgeville bank and repeat. I did this with Super Energy and managed to get around 3,300 shields an hour. I then sell these at 420gp a piece (it can take a few days/a week to sell them), but I have managed to sell them all for around 1,000gp each by just waiting a bit of a longer time. I recommend not trying to sell lower as that drops the hourly effort of collecting to around 400k/ph. The store replenishes it's shields in a matter of seconds so you don't need to world switch. I hope this helps you all get some money together to start flipping more items and maybe get a bond or twp.
