At some point, she doesn’t want to get it. Try working the husband route, everytime she talks about it all, ask if he is ok with it. Help him grow a spine (ask about how he liked the book), and let the person who should be fighting these fights do it. She most likey uses you against him anyways, so help him fight back. (“seattle” is ok with it, and she is so good at saving money, so it isnt a big deal!)
