Samur-Eye: http://www.tf2outpost.com/trade/26069682

Desert didn't seem all that interested in the Samur-Eye and traded it away very quickly. It's hard to say, but it was likely offered.

((370 * 0.9) - (106 + 16)) = 211, rounded to 210 keys

Bubbling Ye Olde Baker Boy:

Quick-sold for 12 keys

http://www.tf2outpost.com/trade/26130856 Buyer is reselling for 15 keys.

It's probably closer to 15 keys as the other seller rejected 14 pure http://www.tf2outpost.com/trade/25217763
