I signed up for another account as mention in the $30 off thread. It didn't work, because no credits or discounts were listed and it warned me not to sign up with multiple accounts. Anyway, I gave up trying and decided to buy some items I'd designed and just pay full price. So I logged out of the new account I'd just created, logged back into my first account and tried to purchase some items in my cart. But now it just keeps looping me back to the login page.
What gives!?
I also tried to unsubscribe the second account so I only have one again. But couldn't find how to do that.
Clear your cookies and cache. I'm surprised Vistaprint even cares how many accounts you have.
