(For underwear, socks, and other items that came in packs, we calculated the cost per item in order to make a direct comparison.) The original shopping cart test, in 2011, revealed Walmart to be the cheapest store for back-to-school clothes, at $218.36 (before tax), and Kohl's to be the most expensive, at $705.13.
