AMHash website does not seem to work properly. Once logged in, if I click on Account or My Orders, I am directed to log in again. Clicking on the buy now button in the store also prompts me to log in again. If I log in again at any of this prompting, I am dumped back to the home tab without having accomplished anything. If there's any way to actually buy anything on this website it is escaping me at the moment. 
Works for me, I bought 20TH just to see what happens. It made the order and its just sitting there waiting for me to pay for it.I also bought 6 PH lol, just need to get my funds together now
Well I'm glad it works for you, but I am having the same issue in Chrome, Firefox, and IE. All I can do is endlessly be prompted to log in over and over whenever I try to do something.
Can confirm, it has also never worked for me (at least in English) with a variety of different browsers.
This is shoddy guys. Don't open up a bitcoin e-commerce site without knowing exactly what you're doing ... and testing it thoroughly first.
