There are a lot of good ideas here but they all involve changing flight schools and that doesn't sound like an option for you. The best way to save money is to avoid repeating lessons. This means showing up ready to fly. Lots of ideas on how to do this have already been mentioned but one of the most effective has been overlooked. In a 141 school you should know what your next flight lesson will cover. Find another student that is a lesson or 2 ahead of you and ask if you can observe their flights. Not only will you have a head start on your lesson but you will get so see mistakes and you don't have to pay for them. This is easily the best way "come prepared" and in the end it will save you lots of $$$.


Good Luck!
