A medical supply store or a REALLY good drug store (one that carries some medical supplies). There's an AWESOME drug store one town over from me (medical supplies, compounding pharmacy, homeopathics, big breastfeeding section and an LC on staff) I was pysched when I found that they sold peri bottles.<br><br>
After my first birth I had felt so gipped that we're not introduced to peri bottles a lot earlier in our lives, like maybe when we first start our periods. They are just so great to have on hand.
