A package having a built-in promotional piece is provided. The package has a wall comprising an outer layer laminated to an inner layer. The piece is located between the layers, and held in place by the surrounding lamination. One layer may be a strip having the piece preattached to it so as to cause the piece to be placed between it and the remaining layer upon attachment. A window may be provided for viewing the piece from outside the package by making the area of the outer layer contacting the piece transparent.
