absolutely millions a week as i have a 19 year old daughter who uses it for everything...eg: a boob tube, a skirt, knickers, leg warmers, removing make-up, breast enlargement etc etc...
but i have used the sains 40p ones i they do last a week and theres 4 of us,well one is still in nappies,40p for a week is pretty good. but i do like the bogof offers. bogog get it? charmin is good quality though,and 24 pence a roll aint bad. i do like a good bogof offer especially when its things that you need. i went to the chemist about 3 months ago and needed calpol for my kids and blow me down with a feather it was buy one get one free! couldnt believe it bought 6 but only actually paid for 3.now thats a bargain.
