Here's some tips that helped hubby and I afford what our goals were:
Coupons - learn to use them. I'm not talking about those crazy coupon reality shows. I'm talking about using them on things you buy every day. You can find coupons anywhere for almost anything. Don't use them on things you have no intention on using. But for things you do use, they are FREE money.
Change - Don't discount this a all. Even pennies. They add up. Find change in a parking lot? Pick it up, toss it in a jar. You'd be surprised at how fast it can add up.
Recycle - If you need something like say a bridle. Don't buy new. Look on craigslist (be careful), consignment shops, 2nd hand tack stores, etc. Make sure it's in safe condition wise and not going to break. Clean them up and many times you can find things just like brand new.
Freecycle - I am not sure where you live but here's a link ... The Freecycle Network
.. find a group in your area and those things are FREE. Be sure to give something back though. That's why these types of things work.
Budget - Define things you really need vs things you want. Wants are "nice to haves" but if you are going for a specific goal, they are not needed. Decide how much you can save and never fail to put that amount away where you can't get to it easily.
Hope this helps you some on the financial end of things. Good luck! It looks like a great program :)
