Probably have to overpay a little for haunted hats nowadays, as they either sell as sets or people don't want to sell them with h'ween coming up.

People overpricing sets shouldn't increase the value of a singular item

I'll confess to getting one for 2.66 a week ago, but it was a good thing I got in early because other traders were offering 3-3.33 ref within 24 hours. Also the owner was the original owner, so he may have been going off spreadsheet.

I overpayed yesterday for the haunted undercover but I dont even care since it was the last piece missing from my sets, but I agree haunted hats (not misc) are getting really hard to get, and some people buy cheap sets just for the hat, so yeah the more the sets go up in price the harder is to buy the hats alone, and the price goes up, so happy my set is complete so I don't have to worry anymore ^^
