Is this a safe site to purchase the Iphone 4 from?

I've been wanting an iPhone 4 for a long time. I was just wondering if this - http://www.rakuten.com/prod/apple-iphone-4g-16gb-black-verizon/239960770.html?listingId=282149807 - is a safe site to buy it from? (I would of course use Paypal) It's refurbished but I don't really mind. I've never ordered anything online that's more than $100 so I was just wondering if it's a reliable site.

Yes, you can tell if a site is legit by looking it up on Google, and if it comes up first it's real. Also the iPhone isn't being sold for $5 so it should be fine.
