I think the best way to save $ for back to school is to shop at garage sales! I don't like to skimp on my daughter's health, so I try to buy healthy foods, and we all know how expensive that can get, but it is worth it to me. I do, however, try to avoid waste by only packing what she will eat. Buy for supplies, clothing, etc... I hit my local garage sales. It saves us a ton of cash, and is a great recycling technique.
