The ease of use, customer service support is excellent! I love everything about this program - it's easy to navigate through your account using their intuitive system for creating listings/products; they are very responsive in terms what you need when there has been an issue (i have had several issues but nothing big). It would be great if we could upload our own pictures or make edits directly into products like other sites do now days!! They offer so many options that allow us as retailers flexibility by allowing certain items sold out without needing additional stock from them which helps keep costs down while still being able meet customers needs at all times during sales periods etc etc.
