all the potions

As you all know, all the special potions are going into retirement, and I plan to gather as many potions as I possibly can. Every time that a potion goes into retirement the price goes up and then they don't appear in shops and it's just a big mess. I am currently trying to get all the retired potions I can get like rofling potions and poera potions. The only way I can et these items is if you guys help me. Plz help and i will help you.
