Sales 26 and 27)

https://marketplace.tf/items/tf2/31002;5;u116

$49.99 / $1.83 = 27 keys

$51.99 / $1.86 = 28 keys

Sales:

27, 27, 27, 28, 28 and 34

Calling 34 high due to unsolds and lots of lower sales and buyouts

Including 26 in the range (from sale 9) as we have a lot of sales to buy orders at 25/25.5/26 keys. Buyers currently are 25.5 keys, which rounds to 26 (can't have decimals in the range above 10 keys otherwise I'd make this 25.5 - 28)

Thanks =)
