If I complete the Ardougne elite tasks (and then speak to Aleck), do I have the option to postpone receiving the experience lamps? I would prefer to use the experience when my runecrafting reaches 85, which won't be any time soon.

I thought the red xp lamps were bankable?

 

Even if not jsut don't use them and possible they will have a destroy item tht will reset them to Aleck or something

Try banking them in a F2P world if a members world doesn't work? Or just don't speak to him until you want the lamps.
