Purchase beautiful case for my iphone 4s?

Yeah, as what you have seen, I want to purchase beautiful case for my iphone 4s to protect my iphone, does anyone have the experience to buy the case? Could you show me one which is free shipping.

Amazon would be a great place to look. If you have Prime, the case should ship for free
Kate Spade has some cute cases, but they are a but expensive. If you are looking for a higher quality case, try Apple's website. I just got a really cute one from Charming Charlie's. It was only ten bucks! You could also try a screen protecter. Zagg makes an awesome one that will protect your phone from practically anything. They have a front and back set so you wouldn't have to get a case. I've seen them at target.
Hope I helped!
