Added together is 12.49/7 = ~1.784

9.54/1.784 = ~5.35, rounds to 5.5.

Worth noting 2 of the marketplace sellers dropped slightly, to $9.40. 9.4/1.8 = ~5.222222.

I think we can call this close enough. If deemed absolutely necessary, or if one sells, I can re-suggest. Don't wanna jump the gun in case key prices drop significantly on marketplace, making the resuggestion redundant.
