FoxKit: Upsell & Bundles App

I've used this app in conjunction with the Minimog theme and I have since found it 100% essential to building a successful ecommerce store. It offers so many useful add ons and functionality for a store that it's now an essential install for every store I work on and build. Some of the features like the product bundles and free shipping goal I use on every store now as they have such a good impact on how I site works. Recommended for everyone.
