Looking to update a 10 month old price, basing it on offers given to the same hat.

Offer of an earbud (from me) and 1 earbud + virus doctor from another user.

Got offered a bud + 2 keys (the owner said he was looking for a bud + 4). It was listed for 27 keys in the classifieds on the 27th of May, screenshot taken 3 days later.

Summary: I think a slight 1 key shift up in price is ok.
