Given the miracle of the pill, I can get by on whatever's cheapest--usually samples or free from CVS. I've had the same box of supplies for over a year.
I can understand that everyone's got their own needs and should use what works best for them, but I never understood folks who insisted on only the name brand stuff without ever trying the cheaper alternatives.
Every once in a while someone will spout off a huffy "I could NEVER use generic tampons" like they're some kind of high end luxury product. They're tampons--it's not exactly a glamorous job, you know?
