Selling Halloween Items!

I don't know the value of these items so just offer, I don't want this to be an auction because I'll get banned but I don't know what else to do. I'm new to these forums so I dont know how to sell things I don't know the value of.

I have:
3 Ghosts in the box
3 Transfigmogrifier Tonics
9 Witches Brew
7 Vials of Abstintene
8 Squash Serums

If you want to know what they do just ask.

Il take the witches brew and Absinthe - there lvl 1 alcohol - for 100g each IGN Tempus Reborn.

FY info the other items are change appearance items temporairily - I wouldnt take less than 250g each
The Ghost in the Box perhaps a bit less (its like a boo! firework)

Brew + Absinth for 120g each, PM Madame Mysterica
