When It Is Worth It

BOGO 50% off pays off when you genuinely wanted two of the item — socks, shampoo, kids' clothes — and the two items are close in price. If you only needed one, a straight 30% or 40% off sale on a single item usually beats it, because you are not spending extra money to "save." Use the calculator above to compare: enter the pair's total list price and the effective percentage to see the true savings in dollars.
