It really depends on the toy and the toy materials.
The only thing I do enjoy out of all the free stuff that has been available over the years is the wipes. They are the only thing I have actually looked forward to getting.
The other free stuff... I have no real need for it so there would be no point.
BUT... I have included some of the free stuff just to get the free batteries that come with it.
Not to mention... as an international customer but sometimes, the free toys costs more overall in postage.
