Kirkland diapers ?

ok so i have always used huggies or pampers for my baby . lately i have been trying to cut cost down so i started making my own wipes , cooking my own baby food and all . i am thinking to switch to kirkland or cheaper brand for diapers ? also i was thinking to use reusable diapers . which one is better in cost and leakage . and for reusable diapers which ne is cheaper compared to the fact that i will have to wash them everyday in the dryer which is a little costly itself . anyway which one is cheaper? thank you .
