The magic items described in Chapter 7 all have prices. The assumption is that, while they are rare, magic items can be bought or sold much as any other commodity can be. The prices given are far beyond the reach of almost everyone, but the very rich, including mid- to high- level PCs, can buy and sell these items or even have spellcasters make them to order. In very large cities, some shops might specialize in magic items if their clientele is very wealthy or includes a large number of adventurer [sic] (and such shops would have lots of magical protections to ward away thieves). Magic items might even be available in normal markets and shops occasionally. For example, a weaponsmith might have a few magic weapons for sale along with her normal wares.
