Where can you do your back-to-school shopping tax-free?

Nothing strikes fear into a child's heart like advertisements for back-to-school sales in midsummer. But it's not always heartwarming for parents, whose wallets can get hit hard.

Families with children plan to spend an average of $684.79 each on back-to-school shopping, according to a National Retail Federation survey. Some states give parents a break with summer sales tax holidays on school supplies, clothes and computers.
