I researched a lot of shopping carts before deciding on Cart32. Other carts either cost too much and offer more than my small business needed or cost very little but have no features.
Cart32 is perfect for my small business with a lot of features I will use once my business grows. Setup is easy and I have full control over my website design. Cart32 has real time shipping rates, real time credit card processing, several discount options and several tax options. Their support is superb also!
