Are you cashing out? Why the sale?
I'll offer $.02 per craftable normal weapon.
For the balance of the backpack I'll offer on lowest spreadsheet listed price at $.35/refined.
Meaning if an item is worth 1 refined at the lowest point of the spread I'll offer $.35
If worth 2 refined I'll offer $.70
If you take those offers I'll offer $9.00 on the Bill's Hat
Crates you throw in.......
Uncraftable stuff, Scorched Keys & Goldfish - You keep
Refined metal - $.35/each
Keys - $1.29/each (What I pay on SourceOP)
Essentially I will buy your backpack using the spread above.
