Money and shopping.

The city runs on credits. Everyone starts with 50.
  wallet                   your bank statement: your balance and
                         your last 20 transactions (credits too)
  pay <person> <amount>    give some to another player
  vault                    at a Neon Mutual branch: store what you
                         can't carry (store, retrieve); one vault,
                         the same at every branch

Some people sell things. Where they are:
  list                     see what's for sale, and the prices. On the
                         webclient it opens a shop window: point at an
                         item for a summary, click it for its picture,
                         stats and description, and BUY (a box beside
                         it buys several at once). Gear you can
                         wear is compared with what you have on there:
                         green is better, red is worse. Its SELL tab
                         lists what you carry that they'd buy. Moving away
                         closes it (list classic for the text list)
  buy <item>               buy one; add "from <vendor>" if two sell it
  sell <item>              sell something you're carrying

Vendors buy back what they sell at half what they charge, and
anything else of the same kind at half what it's worth: an arms
dealer takes any weapon, a tailor any clothing or armor, a
ripperdoc any implant, a food cart any food (but not chips or
stims). A few dealers buy anything at all: sell them your loot.

Every vendor buys junk: the odds and ends creatures drop, from
bottle caps worth a credit to keycards and neural cores worth a
couple of hundred, and creature parts like tails and fangs.
sell junk sells all of it at once (the shop window has a SELL ALL
JUNK button, and so does a vendor's menu), but never anything a
quest of yours still needs. The shop window lists what you carry that the
vendor would buy, and for how much.

Examples:
  wallet
  list
  buy noodles
  sell 3 rat tails
  pay Nyx 20
