Miscellaneous Items and Services
Exactly what items are available for sale varies greatly based on the setting - blasters and spaceships aren't available in a typical fantasy game, and a sci-fi game probably doesn't have many places where you could buy a sword. Items like food, lodging, and clothing are available in just about any setting, and in different levels of quality according to the price category.
For example, you can buy an inexpensive meal, a moderately priced meal, an expensive meal, and so on. An inexpensive meal is light and probably not very nutritious. An expensive meal is available only in nice restaurants in certain locations. An exorbitant meal is probably a feast for a crowd, with the finest food and drink available.
Lodging for a night is similar, although the bottom end starts out worse. An inexpensive night's lodging is probably a flea-ridden mat on the floor of a room filled with other lodgers. Moderate lodging is usually a private room with a decent bed. Very expensive lodging might be a suite of rooms with delicious meals and personal services (such as massages and laundry) included.
Inexpensive clothing is just a step up from rags, but moderately priced clothing is decent enough. For a formal party, you'd want expensive clothing. Rich people likely wear very expensive clothing most of the time, and put on exorbitant clothing (and jewelry) when they go to a fancy party.
Typical equipment is about level 4 - less if it's of inferior quality or materials, more if it's of superior quality or materials. This means that in a setting based on the distant past, the default level might be 3, while in the future it might be 5 or 6. So an average serf's tool in the Dark Ages is level 3, easily broken, while an average tool on a space station is level 6, made of advanced polymers. A tiny item like a ring or watch will usually have a lower level, and a large item like a car will have a higher level.
The context in pricing often matters. In a real-world setting on modern-day Earth, a matchstick is almost worthless (many establishments give away books of them), but it would be very valuable in an Iron Age or Stone Age society. A sword might be expensive in a fantasy setting, but mostly worthless in the far future other than as a collector's item (although it hurts just the same if you're hit with it), making it either inexpensive or very expensive. A motorcycle would be expensive in a real-world setting, moderate at best in a future setting - again, unless it's a collector's item - and utterly priceless in the Iron Age (as long as the fuel lasted) if it somehow found its way to 1000 BC (where it would be an artifact). In a fantasy setting, a magically fueled motorcycle might have the same value as a flying carpet or trained gryphon.
This is why you can't have a standardized price list that applies to every setting, genre, and time period. It's all about context.
