The fact that this has so many options for customization allows me to be able to change things as I go along without having to worry about breaking something or finding myself in some obscure area of coding. It's very easy to use too - you can literally drag-and-drop items into your cart just by clicking them! No need to mess around figuring out which box goes where etc...the instructions are fantastic and there was never anything confusing when it came time to customize my site. Honestly couldn't think of ANYTHING bad at all!! There isn't much downside really. If you're looking for an intuitive way to set up your website (or even if not), give cubecart a try. You won't regret it. We have been using cubes carts since 2012 and we love every second of working together.
