PC on Frostie Tonic

Hey sorry if there's already a thread on this (I searched and can't find it)

But does anybody know how much these go for I tried asking in towns and got no replies thanks

i also did a search here and couldnt find anything.
my guess would be 250g-300g like some of the other tonics, but if the frosty tonic is just for this wintersday in july, then maybe much more!

They run for 1-2k each when bought from other players.
