How to actually meet a breeder?

I've been in contact with a rat breeder for a month now, she said she would email me when the litter has arrived, but I emailed her yesterday and it turns out they are already available for adoption, so she must of forgot to email me in advance. It's my first time with a breeder and i'm not sure how i'm suppose to talk to them, the one i've chosen is quite blunt and I feel awkward asking this stranger where her house is etc. I've asked her when is best for her, and she'll reply but I have a feeling she won't get straight to the point and tell me her address etc. I'll most likely have to ask, and please tell me how to do that without sounding weird?
