That comes up to about 7 keys. That's... Actually a reasonable offer for an unpainted Bill's, actually.

Wut. How'd did you get 7 Keys?

> If a Weapon = 0.5 Scraps
150 * 0.05 = 7.5 Ref (3 Keys)

> If a Weapon = 1 Scrap
150 * 0.11 = 16.5 (6.6 Keys)

Assuming each Key is 2.5 Ref of course.

I counted keys as 2.33. That's probably how I got 7.
