COB or Formal?

Hi guys,

I was wondering whether or not I should accept a bid from a sorority I like during fall recruitment or if I should wait until formal recruitment to get to know all the sororities? I feel like I may miss out on the process of finding a home if I don’t explore every option. If I don’t accept a bid during the fall from a sorority but then decide in the spring after formal recruitment that I’d want to join is it possible to get another bid? Or will they be like Nah you rejected us already.
