E.Commerce

The top 3 important features for a E-Commerce site are:

User experience - catalog, wishlist, shopping cart
Usability - useful search, filters, sorting, product details
Ease of use - from selecting an item to making payment

Product comparisons can improve a shopping experience — and increase sales. Consumers typically shop for similar features. A product comparison feature on product pages can help them view features side-by-side, instead of flipping through many pages. Many shopping carts are starting to incorporate this feature into their platforms.
