Today on the radio I heard the d.j. talking about a frugal blog where the blogger has put together a Back To School Supplies Price List, at Passion for Savings has put together this awesome list of supplies most kids need. She has listed the retail price, the buy price, and a stockpile price. After all half way through the school year there is always a note asking parents to replenish the supplies at school.
I would print the list out, you can click on the Back To School Supplies Price List (in blue letters) on her blog and it will open up the list in a new tab, then print it out and take it with you to do your school supply shopping.
While you're over there, check out all the deals and coupons posted.
