@Arctic_Tern What I was told back in the days of old, when IRKs were only $5, they were sold in lots of like 300 and VMPs got their own hour was to wait for the clock to count down to 0. Then count slowly to 2 or 3 (I’ll get back to that in a minute) and reload the page. Don’t wait for it to reload. Then scroll and click as quickly as you can, pray you don’t have to prove you’re not a robot by anything other than a click and make sure you have your credit card number already saved on the site. Sometimes it takes less to prove you’re not a robot if you’ve already bought something earlier in the Mehrathon.
Now, about the counting to 2 or 3. It’s all in the timing and will vary based on your internet connection, browser speed, etc. To figure out exactly when to hit the reload, practice with other items to get your timing as close to exactly when the item goes on sale as possible.
