Why jump through hoops to bring a printed present? Unless you really want to do that. My idea: On the way to the party buy a cute birthday card (at the drugstore) and write a note: "gift to be delivered this weekend!" Then go to the toy store tomorrow or order on Amazon an item to be delivered this weekend. (But if you are nervous about not bringing something "to unwrap" today or you just want to be done with it, cash is great too.)
