Blizzy bonk boy: 8 month old price. a LOT of people are selling it for for far under 4.1-4.5 buds

I am aware of the new rule using the last, un-inflated suggested price and am using .9 overpay method

B/o: 3.7

sold for Cauldron bubbles noir.

everytime I click on the "stats" button on the cauldron bubbles noir it brings me to a blank page that says ERROR: you have selected an invalid item. however that hat price is 10 months old. because of this I cant find the original suggested price of the hat. im guessing it would be around 3.2-3.5 but that's a guess so i'll be using the low b/o as proof

B/o: 3.5

bought for 3 buds pure **however** it was on his quicksell trade so this shouldn't count I believe ( http://www.tf2outpost.com/trade/15361081 eleventh comment)

55 keys / 3.45

was bought for planets bonk boy + a bud and a half pure.

2.5-3 = ~2.75 (planets bonk) * .9 = 2.5 + 1.5= 4

there's one on the classifieds for 3.9 buds (63 keys)

conclusion: 3.5-4 buds because low b/o's and a sale at 4 buds after overpay.

on a side note, the last suggested price of this hat was 3.1-3.5 which means this is technically going up in price
