Kohl's $5 off $5 Coupon

If you sign up to receive email alerts from Kohl's (here), you will receive a coupon for $5 off any $5 purchase. Recently, Kohl's also emailed it's customers a $10 off $10 coupon as well. I'm thinking of putting together a Mall Freebie run so I can also get my free sunglasses from Charlotte Russe!
