Sizing and where to buy

I love love love my diva cup. I don't even think the size matters. I use both model 1 and 2 interchangeably. I'm a 30+ yr old woman who gave birth (vaginally) to two children. One of the reliable places with the best price to get it is at http://www.iherb.com/
Use my referral code KAS985 to get an additional $5 off. So the price comes to about $20, including shipping. Best of all it arrives so quickly!
