What are you interested in? I asked for money and opened a checking account. Is there a certain pair of shoes you have been wanting? A cell phone? Tablet? Not sure what your step moms budget is, but the possibilities are endless. Good luck and Congrats!
A VHS player is pretty cheap--That is until it becomes a collectors item due to its rarity, assuming such a thing might actually happen. Another more "practical" gift that not only screams "cheap" but even "don't really give a damn" is a paperweight.
