I signed up today after having a look with my SIL last year. With three kids and three bathrooms for us it's worth it. I got toilet paper, nappies, wipes, conditioner and meat for the freezer. It means I can get a months worth of the staples in one go. I wouldn't get the vegies and salads etc as we wouldn't use it all but the chicken tenders that the kids love were $8 for a kilo instead of a tiny box you get at Coles.
