Buying construction materials from Bandit Duty Free

The methods in this guide may involve considerable risk, including (but not limited to): loss of money/items, unstable prices, and/or slow GE resale. Reason: Construction materials consistently sell far below the GE guide price. The large amount of starting cash and small profit margins may cause you to waste nearly all of the GP spent on items with deflated resale value. You can discuss this issue on the talk page or edit this page to improve it.

Details

The Bandit Duty Free shop, located in the Bandit Camp in level 23 Wilderness, sells various construction supplies at much lower than the GE guide price. To reach the Bandit Camp, teleport to the Edgeville lodestone and speak to Mr Ex to skull yourself. Next, bank all items except teleport jewellery, then teleport to the Wilderness Volcano lodestone and run northwest until you reach the Bandit Camp. Noterazzo is located on the western end of the camp; buy any profitable items and immediately teleport away using the Amulet of Glory or Ring of Wealth.

Please note: The margin of profit for this method may be much lower than the GE guide price might suggest. Construction materials such as the marble block and gold leaf may not sell at a profitable margin (or at all!). The large amount of starting cash required for this method, combined with the potential lack of resale value, makes this method risky and generally unprofitable.
