I am might be biased (well I am biased) but didn’t the best ecommerce platform just get even better?
As part of the BigCommerce Design and Developer Network I get to spend a lot of time for a good number of clients working on both the front end design and the back-end. Always a huge issue is the functionality behind setting up product options. In a simple example a t-shirt is sold in 3 size and 3 colors and even that creates a 3 x 3 grid of options but more likely there are 5 sizes and 6+ colors. The updated BigCommerce version is significantly more flexible and simply quicker to work with.
