Lets say this is your store locator page….
…and a searcher from Chicago lands on it. Normally this would lead to an abandon (because you don’t have a Chicago location) but there may be a way to convert this exit into a sale. Right at the bottom of the page I’d post this message:
“If you couldn’t find a local store please leave your email address with us. We’re opening stores all the time and would love to notify you the moment a local store opens. And because we feel bad for being unable to help you today we’ll email an exclusive discount coupon for you to share with one of your close friends who live near our 14 national stores.
PS: When we open a store near you we’ll send you a discount coupon too!”
