Where is the best place to buy iPhone 5c cases for an affordable price?

I just ordered my iphone 5c and I would like to buy a case but I'm having difficulty trying to find a place that sells them. I would prefer ones that have simple designs (tribal for example) or ones that are simple colored.

Ebay

Simple check Amazon >>http://www.amazon.com/gp/search/ eBay, Best Buy etc…
They have a number of tribal and simple cases that you can easily chose from…

Monoprice has good quality cases:

You can also find a variety on Amazon. Look for cases with good reviews. I got an iPhone 5s case for around $8 on Amazon but it is a fancier case. You can get simple cases for a lot less.
