Re-suggesting once again since polar said that this new range would be much better than my original one for a few good reasons. Thanks for helping polar <3, Hopefully it's all good now. Also big thanks to PPK Flutterslut with providing me pictures to their trade history.

1 of 1 in the world as of now. Also this is my first suggestion! :D

Oh god this is nerve-racking

Sold within a week and polar said it was fine to value it at 4 buds without calculating overpay

4 + 2 = 6 buds.

Most recent 5 sales on SCM are:

$2.01

$2.22

$1.74

Mean Price = $10.4/5 = $2.08

2.08/2.50 = 0.832 which rounds down to 0.83 keys.

6.83/13 = 0.525 buds, which rounds up to 0.53 buds

5.53 + 3.35 = 8.88 x 0.9 = 7.992 which rounds up to 8 buds

Now, I'm quite new to this. So if there is anything I messed up on or something of that sort. Please tell me in the comments below as I would appreciate the criticism so that I can improve on what I've lacked on in future suggestions!
