If the folks are comparing them to something like a JC Pennt pillowcase, that's whole different thing. JCP kid's pillowcase pairs run about 15 bucks, on sale - like they always are. If they're comparing them to hand-made things for adults, you're wide open and I agree with at least 30 per pair. but I know people will pay way less for kids' things ... and buy two separate pairs. who's crazy?
