You can buy MM2 items with real money, though the purchase happens outside Murder Mystery 2 because the game has no built in shop for selling weapons between players.

Buying MM2 weapons is usually cheaper than unboxing them when you want one specific knife or gun, because crates in Murder Mystery 2 carry no guaranteed drop for Godly or Chroma items. Reaching a named Godly through crates can cost more in Robux than the weapon trades for, while buying it sets the price upfront on the exact MM2 knife or gun.

Buying MM2 items sets off no automated detection on Roblox, because the delivery is an ordinary in game trade that looks identical to any other trade between two players. The risk with buying MM2 items sits on the payment side instead, which is why its importatnt that sites verifies its sellers beforehand.

The only detail needed to buy MM2 items is the Roblox username the weapon is going to, because delivery runs through an in game trade rather than account access.

You never need to share your Roblox password to receive MM2 items, because the delivery runs through an in-game trade that only requires your Roblox username. Any seller asking for account access on an MM2 item order is not following the delivery process.

Delivery time on the MM2 shop depends on the trade method and how quickly both sides get into the same Murder Mystery 2 server, so the estimate is shown in the description of each MM2 item rather than being fixed across the MM2 shop. Orders complete shortly after payment clears rather than the moment it does.

You do not need Roblox Premium to trade MM2 items, because trading in Murder Mystery 2 unlocks at account level 10 and nothing else is required.

You need to be online to receive MM2 items, because Murder Mystery 2 has no mailbox or gifting system and every item moves through a live trade between two players.

Accounts below level 10 cannot receive an MM2 item at all because Murder Mystery 2 blocks trading entirely under that level.

MM2 items can be traded again after buying them, since purchased weapon behaves exactly like an unboxed one with nothing marking it differently.
