Is the Marrkt sale open? I only see the countdown, no option to sign in.
UPDATE: It appears that the sale opened early by mistake? I got in to the sale section, added 1 item to my cart, then was unable to more. When I looked to see if I could check-out with my 1 item, I had a 'sale was closed for this product' message.
I wonder if the people who were able to check out with their items will have their orders cancelled?
