A recurring trope in which a staged location is made obvious by the mark discovering that the objects in the location still have price tags attached, indicating recent purchase as well as hasty staging. Usually the con artist or stooge will make up some lame excuse as to why they are still there. Sometimes the mark gets it, and the subterfuge is uncovered, other times the mark is or plays dumb.
- Grand Theft Auto IV: In Michelle's apartment, Niko notices the pillows on her couch still have their price tags on, which Michelle weakly explains away. Niko seems unfazed, but this is a huge telegraph to the player about Michelle's true nature.
- The Game: In Christine's apartment, Nicholas notices smoke coming from a table lamp, and discovers a thrift store price tag smoldering against the light bulb. This leads him to examine the photo frames and the bookshelf, uncovering more of the sham.
There's more than these, but it's hard to find the phrase in context. I'd seen the trope well before GTAIV.
