There should be plenty at the Apple stores
Check the Apple Store app. You are able to check and see which colors are available for in-store pickup![]()
My local Apple Store had loads of silicone cases, I took my leather case back today to exchange for the silicone... First the red, then I changed my mind for the black as it's more subtle. The apple silicone cases do feel really nice though, soft touch rubberised feel with plenty of grip.
Is it easy to get in and out of your pocket? That was my worry with the rubber/silicone case.
