That would be rejecting the bid and would mean she was locked out of receiving another one for a whole year.

This really isn't that different of an answer than the one you've gotten in other threads when talking about your daughter's experience.

Signing the bid card is a contract to accept a bid from ANY of the chapters listed. Even when recruitment counselors are bad about explaining it, it is written very clearly on the card itself.

Snap bids can only go to PNMs who did not receive a bid at all, not to someone who changes her mind.

In short, she can "change her mind" and decline a bid, or drop out of a new member period, but if she signed the card there is no exception to the rule.

None.

But if I ask you again in a different way, will you give me an answer I want to hear?

I was asking because a girl in a different sorority (XYZ) than my daughter's (ABC) had told her they were going to "snap bid" a number of girls who had changed their minds about being in my daughter's. I didn't think that was possible but I wanted to make sure.

Yeah that's not how snap bids work. It's possible there are some other shenanigans going on, but it's not snap bids and it's not with people who signed bid card within the past 12 months.
