sale 3: (ty chicken -> http://backpack.tf/vote/id/56b89fa8ba8d88e318bd04df)

x+43 = 250, so x=207. Make it 210 for neatness.

Taking 210

something to do with a duped scret brown bomber?

Foamy: "Also Im quite sure 30 keys were added to the gibus in the bomber sale. I have a mini at 330 on the bomber, and since the db gibus is nearly outdated, I figured it was worth waiting for another sale since realisticly the sales are pretty far apart:"

Tbh im not expecting this to pass.

If anyone can clarify on that bomber sale, or maybe find other sales, any help is appreciated. Plus, if i were to include the bomber sale that come out around ~300, we need to fix the range.
