I  stumbled upon a great deal with holiday greetings cards and immediately placed the bulk amount in the basket. When checking out, I messed up with my payment method a bit, and ended up redirected to the start page. When placing the exact same order again with the same reseller, I noticed that the computer got numbed. I tried to refresh the page but no dice. Turned out I was locked out of my account due to supposedly suspicious activity on my part. Resolved the issue after three days of communicating with the security support. Still find it ridiculous and frustrating.
