Spah, sappin' my price range! This is my second ever suggestion! [proof below]

After unboxing two of these and attempting to sell a third, I think I've discovered this price is more accurate:

backpack.tf classifieds: http://backpack.tf/classifieds/search/id/52b48d704dd7b81a568b4567

4 keys (x3)

4.5 keys (x3)

4.6 keys

4.7 keys

4.8 keys

5 keys (x22)

5.5 keys

6 keys (x13)

(I won't include anything above that because it's somewhat pointless.)

Note: I've only included proof with offers made since the last price suggestion- no outdated proof here. There are indeed 20 pages on Outpost, but I've only sorted through 2. From those, the only trades I have excluded are ones which have no notes or relevant offers/comments. I have not cherry-picked many trades.

More proof to follow.
