Second as to if he wants to sale magic"which should never be the case" its up to the GM from what I can see as no prices.
From the beta test.
Buying Magic Items
Unless you decide your campaign works otherwise, magic items are, by and large, so rare that no market exists for them. Situations might arise that allow characters to buy or sell magic items. Buying magic items might be easier in a city with a magical academy or a large temple, or in some other location that serves as a hub where adventurers can sell their loot. For example, an apothecary might offer a small selection of potions, or the adventurers might hear rumors of a black market auction where magic items are sold.
Common magic items, such as certain potions and scrolls, can sometimes be procured from an alchemist or a spellcaster. Individuals who aren't normally in the business of selling magic items might want something other than gold in exchange. For example, an NPC mage might create a scroll or adventurers if they complete a quest for her.
Rarity
Magic item rarity serves several purposes in the game. An item’s rarity provides a rough measure
of the strength of the magic in the item as compared to other magic items. If your campaign allows
for trade in magic items, rarity can help you set prices for them. Rarity also gives you a sense of
how likely characters are to find a particular item, given the characters’ level. All that said,
rarity shouldn’t get in the way of your storytelling. If you allow a ring of invisibility to fall
into the hands of a 1st-‐level character, then so be it. It might be an enjoyable feature of your
campaign.
A magic item has one of six different levels of rarity, from most to least available: common,
uncommon, rare, very rare, legendary, and artifact. The closer an item’s rarity is to artifact, the
less numerous such items become. Most legendary items and all artifacts are unique.
