I use X-Cart. I suggest going to https://www.ecartstore.com, which is where I got mine. The owner, Nancy Andrews, is an expert at SEO, and she and her staff can answer all of your questions. It has all of the features that you want, it is very user-friendly, and extremely “SEO-friendly”, if you will. Real powerful, real easy. I am just a novice, but even I can do this. Given the functionality plus the support and expertise, I don’t think it can be beat.
