Interesting. Account/cart access has been giving me an error message for days on many different devices/browsers. I cleared my cache, which didn't help, but going incognito did, so probably a cookie or something I hadn't cleared.
The mobile version seems a bit all over the place (just had 3 of the same account icon in the nave), but at least I can get it now.
Now if only they had other shipping options to Canada these days aside from DHL. Alas, here come the duties.
