I have no money to spend right now, at all. But I guess it doesn't matter. KF is an occasional thing at best now anyways. Still, I'm dissapointed regardless.
Well you know TWI doesn't prevent you from using the weapons if you don't own the DLC (see my example below).
What I usually do if I want to pal around with those weapons is that I ask how much it costs at my perk level, and I fork over the appropriate amount of dosh. Then they toss me the weapon I want.
See how that works?
