Someone is offering to do a "split trade" with me. What is this?

"Split trades" are against the rules! A "split trade" is when a user asks another user to bid on multiple lots. For example, a user might offer to sell you a paint brush for 1.2 million Neopoints by asking you to bid 600,000 NP on the paint brush and 600,000 NP on a junk lot. Then the user will accept the 600,000 NP for the junk lot, but not for the paint brush. It's a scam, and that's why it's against the rules. If you want to sell something too expensive for the Trading Post, go to the Auction House instead.
