It's true, there some similarities, mainly the color and wording, but in this e-commerce shopping cart business to describe the product we always need the words "shopping cart", "create online store", "sell online"... (at least in english)

But hopefully not the same colour scheme and general site layout ?!

Honestly speaking, we've put most of our effort on the back-end development. Our landing page is just Wordpress with a modified custom theme. A designer colleague gave us a help on the branding but the same way many banks / big corps use blue in their logo, green is very standard here. If you think you could do better we're happy to be helped ;) cause every Photoshop crop we do take us half of the day.
