Resuggesting with a new Marketplace sale, and I'm also fixing my sale. Thanks to K1ng for pointing out the Airdog.

75 + 0.5 = 75.5 - 14.5 = 61, which I'll round to 60 Keys for neatness.

https://marketplace.tf/items/1115;5;u3007 - Sale at $160

Keys were $2.02 at the time, so 160 / 2.02 = 79.21, which I'll round to 80 Keys for neatness.
