I tried checking out with a number of different sale items but kept getting "Sorry something went wrong on our end". First I thought maybe they were just out of stock of those items, and somehow that was causing the errors. I tried non-sale items and it still didn't work. I tried logging out, clearing cookies, logging back in, and I got same message when trying to log in. I tried other browsers and incognito, still not working...
Anyone else having problems with the site?
