Cardlis is built to increase connections between Merchant/Retailers and Customers.  Location Services enables Cardlis to match local Promotions and Gift/Loyalty Cards to potential Customers nearby.  In the Case a Cardlis user opts out of enabling Location Services or Location services are not turned on, We use the available address from the User Profile for a location base.  If no address is available, Cardlis will show Businesses and Promotions in alphabetical order.
