With the economic climate today Internet Coupons maybe a way to increase visitors to your website.
The website http://www.shoreguide.info/coupon.htm is just one of many available out there today.
A lot of sites have out of day coupons and even coupons for companies and stores out of business. Try to look for one that is well maintained and is very visible. It makes no sense to place a coupon on a website that no one goes to.
