Be careful of things like this. Remember, the key with making money online is not just the building of a store, but the marketing and being able to draw in interested visitors in order to make a profit.
Yes, this is great that they will provide you with a store but from there, how are you going to market it?
So it takes you back to starting from scratch. Whether or not you are starting with a website, a blog, an online store like this, you name it. Marketing is still going to play a huge factor.
Sometimes I get annoyed by services like this because they make it seem so easy because people are so intimidated by the building and setting up things. So they provide you with false comfort of setting up your store. When in reality that's the easy part (compared to marketing and making money)
You could make your own internet store for free by joining Amazon.com's affiliate program, but then where would you promote it? How would you go about getting enough targeted visitors? Notice out of all the features listed, there are no mentions of helping you market and learn how to draw traffic to your store. Why? Because they throw these ready-made sites at you and send you on your way.
Now, I didn't read through the entire site, but from a first glance it sounds like another one of those "insta-stores" that sounds great on the surface but ignores the hard work of marketing and getting traffic. Not to mention those horrible testimonials on the left side that I hate because they look fake. If I don't see a website address with the testimonial, I immediately assume it's not real.
