Hey all. I recall seeing, for the original iPad mini, several sources for super-cheap plastic back shells. Like just a couple bucks or less per shell. I used to get them from Tmart, as they had them with the smart cover cutout and without. But I can't find anyplace that sells them cheap for the retina mini. Needs the hole for the microphone, and needs to fit the larger device thickness. I've been scouring the case roundup threads, and haven't found anything cheap. See my sig for why price is a factor.
