i got this one for 18 keys, a friend bought it for me

i dont have the item history, it sold the same day i got it

i got this one for 16.5

2 of the $39.99 sales on MP are mine

there is only a single seller at 20 keys and it is 1 day old, that isnt enough to exclude 4 marketplace sales

i think the range should be 16-22 keys (avg 19k)
