Today only, Old Navy cuts up to 50% off sitewide during its The Big Save Sale. Plus, coupon code "SAVEALOT" cuts an extra 25% off all orders, an extra 35% off orders of $50 or more, or an extra 40% off orders of $75 or more. For orders that qualify for the extra 40% off, that beats our mention of an extra 30% off sitewide from two days ago and yields the second-highest extra percent-off discount we've seen from Old Navy in the past year. (On Black Friday we saw an extra 40% to 60% off sitewide.) Shipping adds $7, but orders of $25 or more qualify for free shipping. Everyday Steals, Hot Deals, and some other exclusions apply.See all Old Navy Coupons.
