Old Navy sale 15-20% off

Get 15-20% off during this week's Old Navy sale online through Wednesday, May 12 at 11:59 pm EST, depending on how much you spend.

Get 15% off purchases of $75 or more or 20% off purchases of $100 or more. Use coupon code ONSAVEBIG. The code is only good on Old Navy merchandise. If you can, combine your purchase with that of a friend so the discount kicks in.

The tagline of this sale is "get more, save more." But is that really true?

If you buy exactly $75 worth of clothes, with the 15% off discount you'll pay $63.75, plus tax and shipping. If you spend $100, with the 20% off discount you'll pay $80, plus tax and shipping. So while you save more ($20 vs. $11.25) with the bigger discount, you also spend $16.25 more. Perhaps the tagline should be "spend more, save more."
