So I met this girl at a store, would it be strange if j went back to talk to her?

I went to this store to buy some trading cards and me and this girl had a whole like 30 min conversation about those cards that she was into too. She told me to come back and show her if i got anything good. How should i handle it , go back in a week to see if she's there? And how can i ask her to hang out?

So im sure this girl is pretty geeky like me. Wondering how long i should wait to go back and find out if she's single. Because there's this hidden market place id like tk ask her to go if she hasn't gone before.
