CCL Add to Cart Checkout Links

I was looking for a way to create links that added specific items to a cart, and was also able to add a discount code. This app is super simple and easy to use. It lets you build links with any products, the option to clear the cart for customers so that only the products on your link are added, the option to assign a discount code, and even the ability to add UTM parameters. Support is also very responsive--I had an issue with selecting older discount codes and asked if they could build a search feature into the app. They made the change within 24 hours and got back with me! Works great now. I use these links inside my promotional emails to suggest complementary products.
