Infusionsoft hosted a shopping cart theme design contest. (And we won!)
The design team at Fuseomatic brought you the Vanilla shopping cart theme, now available for free inside your Infusionsoft app. The Vanilla theme was created to be a starter theme template that (with a little HTML and CSS) allows you to easily customize your shopping cart.
So, you can always just use the free Vanilla theme. But if you need something more customized, then why not use an award winning team?
