has anyone ever returned their Divacup [or known someone who has]? i am thinking of trying out a Lunette and, if i like, i would definitely want to at least try to return my Divacup for a refund. as far as i can tell, i havent found anything that suggests Lunette has a return policy which will put me in quite the financial pickle if i do turn out to like the Divacup better. i'll just have to deal with it if that happens to be the case. was the process of returning it difficult/expensive? thanks in advance for any advice!
