Advice for screening Dommes

I'm new to being submissive. I was always comfortable being dominant if that sort of power exchange happened. Recently I met a Domme online and she seemed perfect-except she wouldn't answer any of my questions. I never saw a picture. Then she began talking about me purchasing a "training kit" which threw up red flags for me, and at this point I threw the BS flag and pulled out.

I didn't feel any trust was built her direction and that seemed out of place. Is this typical? Did I overreact? She never did answer any questions. lol
