Excellent
Now make her stick to the one month. Once she looks and can't find it she will stay with you because each month you are still cheaper than the others.
Doing the increase over five months is most likely going to cause you problems with her. It's five opportunities to protest. You have just received her first round. Have it be her ONLY round.
