This time of year the office supply places as well as retailers like Target and Walmart are trying to capture the spending of families on supplies and clothing for the upcoming school year by offering really cheap school supplies which may also be useful for your business. Top that off with many states offering a tax free holiday for certain types of items and you can snag some real bargains.
My state is limiting tax free equipment and clothing to $50 per item I believe, so no computers in the bargains here. But this is the time of year we find good sales on underwear and summer clothing and no sales tax makes those items even better values.
