I like to think that I am frugal in most areas and we certainly take it seriously with things like our https://theminismallholder.com/no-spend-year-get-the-challenge-started/ and how we are looking to make real changes. If I buy all of my sanitary pads from the cheapest places I still think each month would cost around £10-£15 depending on how shocked I was to find myself caught short. A pack of ten like these ones Women Hygiene Sanitary Pad, Feminine Reusable Panty Liner,Bamboo Cloth Mama Menstrual Sanitary Nappy Towel Pad (25.5 x 18cm) (10PCS) will cost less than £20. SO I think I will need two of these for a full months period. This means I was a bit clever and bought one pack and mixed it up with the odds and sods I had left over. This also served to remind me how much I hated the scrunchy, crunchy, plastic, sweaty ones. Three months in to the new way of doing things and you will have broken even. They will last around five years if hand washed. I intend to machine wash as I am not lazy, just realistic. But if I waned to hand wash each month I have information on that below as well.
