http://www.myfitteds.com/ i clicked on random ones, and they all went up to size 8...so i'm assuming they're all like that...or i just got lucky. hahaha. there's also free shipping if you spend $50. i just saw that on the side bar.
http://www.neweracap.com/landing.php?page=men59Fifty&groupName=Men59FIFTY the New Era website. it's weird...i googles new era fitteds and this didn't come up. haha. only when i googles fitted baseball hats their website came up. haha i didn't even think to look there. but not every hat comes in an 8
those two seemed to me to be the best sites that seemed trustworthy. i hope this helps you!
