Old Navy is having a great sale right now.
Today and tomorrow only (7/26-7/27) you can get adult tank tops for just $3.00. I am not sure exactly what style of tops but the original price is $8.50-9.94.
They also have t–shirts and sandals priced at $6.00 and shorts for the family at $9.00.
There is a limit of 5 per customer and this is in store only.
Also through Sunday, you can get $10 off a $50 purchase when you show the coupon here on your phone in store (scroll all the way down).
