I've been to several Walmarts in the area, and it's hard to find someone who even knows a new IPhone even came out, let alone have cases for them... not sure how all these people are finding them at their local Walmarts...
I went to 4 different Walmarts before I found a Frequency. The electronics areas are a mess with everything scattered all around. Don't even bother asking someone in Walmart for help.
