I've used many DNN carts in the past, even was victimized by the whole AliCommerce fiasco....from my experience SmithCart is hands down one of the easiest and most flexible carts to set-up. The check-out process is very user-friendly and all of my client's customers can get thru it with ease. Other carts charge a premium for real-time shipping look-up, multiple tab prod description, or rich campaign functionality, but with Smith cart these are standard features. Another key distinguishing feature is the SEO optimized product pages. This is key for getting your products at the top of the search engines by tagging them with key keywords. Don't take my word for it....see it for yourself at http://shop.madamewalker.net Thanks David and Smith Cart team! ~ DeShon
