Where can I get a melt iPhone case?

What store? I know amazon and eBay but they take too long to ship and cost a lot.

Actually ebay is better. When buying just choose US sellers, so you avoid Chinese sellers, and then choose a priority shipping, or if don't offer ask them to ship it via express or priority and that you will pay the extra. The cases on eBay are way cheaper than most sites, apple store, and retailers in the mall, etc.
