Deals and coupons sites have been around for a long time. As long as you have the best coupons, you are going to have a growing audience. With themes such as DeCoup, you can give your website an attractive look. It lets you import data from DataFeedr and MyCommerce. Visitors will be able to submit their own coupons.
DeCoup is AJAXified with infinite pagination. It is responsive and ready for mobile devices. The theme supports RTL languages. Just like popular coupon sites, you can hide your coupon codes and show them only after your visitors click on an offer.
DeCoup is a paid theme by a Power Elite Author. You can download it here.
