Today only, until 3 pm ET, Old Navy cuts 30% off sitewide via coupon code "AMPM". That's tied with our mention from two weeks ago as the best flat-rate sitewide discount we've seen from Old Navy in the last year. (We often see sitewide discounts from Old Navy but usually not as high as 30% off.) Shipping starts at $7, but orders of $50 or more (before the discount) receive free shipping. Some exclusions apply.
