Markets and Merchandise (Pathfinder Edition) is a collection of useful information on market, what you can buy at them, and wide varieties of things to buy. The Pathfinder conversion (this was originally written for a different system) is rough on a few mechanical things in the weapons, armor and alchemical sections sections. Even with those flaws it covers a considerable amount of useful territory such as currencies, a wealth of interesting trade items, prices for services from the profane to the sacred. I hope Avalon Games revises the mechanical sections noted above so that I can wholeheartedly recommend this product.
Disclosure: As a featured reviewer for RPGNow/DriveThroughRPG, I received my copy of these products for free from the publisher for the purpose of these reviews.
