4.33 | 4.33keys | 3.45 | 3.45 | 4.02 | 4.26 | 3.45 | 4.08 | 4.31 | 3.22 | ~ Not going to include these sales in the price range as they're a bit too high

Going with 3.15-3.25, as 3 keys look too low atm.

Sales:

3 | 3.25 | 3.15 | 3.20 | 3.20 | 3 | 3.15 | 3.15 | 3.20 | 3.20 || 3.25 | 3 | 3.15 | 3 |

Let me know if I missed anything or if there's something I could improve on, Thanks :)
