When Marv is talking to Harry about the toy store robbery while they are skating, Harry holds up a newspaper with an advertisement for Duncans Toy Chest. Marv then says that they should rob it because its five floors of cash. Well, nowhere in the advertisement does it say anything about five floors, and when you see the actual store, it's obvious it's only two stories. Plus, the only cash registers in the store are on the first floor!!
