I can't resist free stuff and dollar stretching opportunities. I not only want the most for my shopping buck, I want it to sit up and bark! That's why I love these back to school promotions from OfficeMax (click for details). First, spend $150 and get a free $58 value 3-piece bag set. Enter promo code "FREEBAG" at checkout. Also, buy certain ful backpacks, daypacks and laptop backpacks--Tremor, Sweet Melissa, Heartbreaker-- on sale for $18.74-$29.99, and they come stuffed with free school supplies. Links below say $24.98, but backpacks have been price-reduced even farther, saving you 53%! Oh, and orders over $50 get free shipping. Already bought your kid's backpack? Buy another for next year. Or buy one to donate. Operation Christmas Child is gearing up for their annual shoe box giveaway event. You could donate to Toys for Tots or church giving trees.
