I think @stickupboys collect the mini-figures, so may be interested in trading. We've got a load that the kids had. I do have a set of Dr Who figures (non-Lego) that are still in the box. Definitely keeping that.
That's sick, well worth hanging onto them, especially if they're in the box.
I'm going to carry on picking these up when I see them, I have a guy I'm going to be buying some Halo stuff off, and he collects Lego so I was going to reach out and see if he'd be interested in any as a trade and knock the price down a bit.
