This is web design built for idiots, and maybe on that it succeeds. Their site building software is totally nonsensical and is totally unlike any other design platform in existence. If you want to spend WEEKS learning how it works, good for you. You'll have a rudimentary site that you're wildly overpaying for. And then you'll have a lot of knowledge about an interface that will be useless everywhere else in the world.
These guys are masters of taking your money for things that should be free (like rollovers or carousels), and then frustrating your guts out with their horrific — let me say that again HORRIFIC — customer service. I've never worked with any company who cares less about its clientele than Wix. Maybe American air carriers are worse? Probably not. Working with Wix when there's a technical issue is a hellscape. I regret ever using them and am actively working to escape.
