I always take advantage of the back to school sales to stock up on office supplies (and even gifts sometimes as they have plenty of things I know kids that would make use of that I can give to them for various occasions around the year!). I make a point of stocking up on things like Pens, paper, notebooks, Staples and even printer ink if they're including that in the back to school sale. I find it helps you to save a lot of money throughout the year. Do you take advantage of these sales? What sort of things do you stock up on?
