Potionomics: What is Available?

Prices and Availability are Guidelines not Rules

  The prices and availability assume you are in a relatively friendly area in relatively peaceful times dealing with neutral but polite people.   "Commonly available items" are frequently manufactured and stockpiled in quantity during peace time   "Relatively common available" are not stockpiled in quantity, but it's not usually very hard to find someone who can make them and asking for it well not normally raise too many eyebrows.   If there is a war or other hard times, prices will probably go up. If you are buying items from your own allies than prices will probably go down.   If an area is experiencing war, all potions will go up in price, especially healing potions and augmentation potions.   If an area is especially concerned with spies and criminals, it's harder to find potions of Disguise Self, Fast Movement, Fly, and Invisiblity legally.   Even if you want commonly available and fully potions, if you want to avoid broadcasting "I'M AN ADVENTURER!" to everyone in the area, you are going to have buy things through back channels which increases the time and expense of the your shopping trip.   Sometimes local conditions affect prices too. Areas with powerful temples probably have wider availability of potions and scrolls for whatever the local theurgists are good at.   If an area's culture really looks down on type of magic, buying a magical item of that sort is going to be a lot harder.
