good suggestion :)

Hue hue funny number

I'm staying neutral, but for a hat worth 167 keys already, is a 2 key increase in price really necessary?

Not a fan of using a sale like this here, but since its definitely the most valuable part of this trade, I guess this'll be okay. No other sales happened, and the cosa has a relatively tight range at the moment. Discrepancies in that price that would be passed on to this hat wont be significant enough to make this exceed the average margin of error.

Also, in case youd be interested, I found a string of suggestions thats doable from when I was checking out the cosa:

Secret charmers sold for burning cosa (~295)

It also sold for spellbound charmers (~200) + aussie ambassador (~16) + spec ks big kill (7) + spec ks black rose (~15-20 ish (displayed price is bs btw)) + hot ft blitzkrieg knife and an 1 key strange.

if the knife has a mini, this sale could be used with the cosa sale to give that a range. If it doesnt get a mini you can use the cosa sale by itself since this should be close to that either way.

Secret cosa also sold for a GE vive (outdated)

I didnt check any other sales on the vive, but you could use the secret chapeau as a mini for it or update it as a whole (if theres other available sales it can get a range, if not, it can get a flat value from the chapeau). The vive sale is the only post-hype sale on the dog and the dog isnt back on the market, so if you can price the vive (or use the chapeau as a mini on it) you can use that for the salty dog.
