Quickflip here:

Nep bought it for a Frostbite Employee (42)

Then sold it for a DBD SnS (Outdated at 54, "mini" at 50)

Sold for 40 pure (yes I checked every key >_<)

SnS mini:

Only other recent sale is for a DBD Warhood, which has no sales.

Current seller at 50?

Sales are 36(quick), 38, 40(pure),42, 45, 47, 47, 48, 50?,55 with a 3 week old seller at 38

I'd go 38-48 here. 55 seems to be an outlier and the sns sale supports the highend.

Not that hard really. :P
