Yep, right now it's a beta version. Still in testing mode, but man it's coming SOON!
Hopefully it'll open in a week or two, but with an e-commerce site and websites in general, it's hard to pin down an exact date for the launch, because bugs keep on popping up. It has to go through a strenuous QA process to make sure all pixels are lined up correctly and functionalities work in all browsers, old and new. It's a lot harder than people think.
It's getting there though. As you can see, it's COMING!
Exciting times around the corner. Keep the faith!
