Upvote, has proof, and a lot better than the 5.2 suggestion

managed to help a friend selling one, i often received 4 bud unusual offers

Again... for this hat. It is worth 5 + buds. Unreal gave me over 5 for it in unusuals and pure. And these are my past offers. I've been offered a Hearts milkman which is 5 buds, an Eerie hallmark which is a little more than 6 buds, a Blizzard Bonk Boy + Stormy Storm Bombing Run + Sweets (#1337 Team Capt) which is more than 5 buds, a Hearts honcho + 1 bud which is 5 buds, a Stormy salty sea dog + orbit fire tossle which is over 5 buds, and a scorching hotdogger which is barely grasping the 4.8 bud range. If you want I can post the trade with these offers on them.
