In my opinion I feel that its very difficult to figure out which which shopping cart software best meets your needs in todays ecommerce platform market. If you are considering starting your own store, then I would like to suggest you to compare with different platforms such as Shopify, Bigcommerce, 3dcart, Volusion and Big Cartel.
I would also strongly recommend to consult with EcommerceMix Team to get the help for starting an online store by their Ecommerce marketplace scripts and to make use of top best Ecommerce platforms.
