I think World Market has those simple chocolate "open a door each day and get a piece of chocolate" advent calendars. My son (3.5) got two this year. We also have a magnetic calendar where each day my son puts a magnet to cover up the date, so today he chose to put an angel on the number 3. We also have a wire thing that has beads - so each day we move a bead to the other side. Christmas day has a bright yellow star.
