Remember my post about Old Navy Halloween costumes the other day? If you didn’t buy, you’re in luck. Today only (Aug. 19) Old Navy is offering 30 percent off all online purchases. Enter the code ONFALL when you check out. If you buy on Aug. 20, the coupon code will be worth 25 percent off, and then 20 percent off on Aug. 21. With this discount, a $29.50 costume would be about $20.

Pair this discount with some sale items – like the cute women’s scoop-neck, perfect-for-fall $10 tees and you’ve got some great deals. Shirts for $7? Sounds good to me. This would also be a good chance to shop for back to school without having to brave the mall crowds on tax-free weekend.

Shipping is also free if you spend $75 or more. Remember, any items that don’t work for you can be returned to an Old Navy store near you.
