I’ve tried the app, the website, etc. I always get an error like message when trying to sign in with Amazon. The problem is that some of the items you have for sale today requires you to sign in with Amazon prime. LOL, oops! That ruins those sales!
EDIT: When trying to log in via Amazon it says:
“Looking for Something? We’re sorry. The Web address you entered is not a functioning page on our site”. It never redirects you back to Woot or signs you in.
