Sometimes during a session, a PC will want to buy or acquire something he doesn’t already have.  Rather than tracking cash and exact home inventories, we will rely on a character’s Wealth or Resources attribute.

Your first option for handling the purchase of an item or good is simply to go by declaration—a player can almost always declare that his character has or can reasonably afford anything that’s 2 levels or more below the character’s Resources attribute or, if the character has another skill that might reasonably justify possessing a certain item, 1 level below Resources.

For anything higher, or in any case where the item in question is rare, restricted in legality (like, only for military or police use), or has to be acquired within a certain timeframe, a roll can determine whether the item can be acquired.
