The refills for Diaper Genie cost about $10 per one insert, if you don't buy the value pack or buy them on sale. This is the FREE version of the refills.
What is so nice about doing this, is that it is completely FREE! The only thing that is not so nice about it doesn't hold in the smell in as well. But it is better than having a fresh poopy diaper fermenting in your face. But you can solve this problem by adding some fresh smelling sent in the diaper genie or you can spray it down every couple weeks.
