I got it. This thread was a bit all-over the place, I posted in the wrong forums initially, then posted to have it moved, then I thought it had disappeared etc... sorry it's badly written.
Basically a guy was offering a nobles deck for 7k, I didn't have that much. I offered him 6.5k and he turned it down, fair enough. I then thought about my titansteel bars and offered him 6.2k plus the titansteel bars, which he went for.
I know Alla's price is around 11-12k, but I've found that the prices on here can be wildly optimistic, so was wondering whether I got a good deal or not.
