Seems like you both are right , I just tested and it's not working at all . Maybe they are on maintenance or something .
However it was working just fine yesterday and I sold all my points to minifrij & all went fine and smooth , so I'am afraid I can't help you even if the website is back to work . You are free to check the shop when it's back to work though
EDIT : what the hell It's just came back to work , you can check it now
