Once your web page starts loading slowly, that means you're too late already, just close it and walk away, 'cause by that point, the first 3 people who entered the site already bought out the stock that's available.
I know I'm not the only one doing this, but I have the pages auto-refreshing constantly, I have no idea how I didn't get in though considering...should've seen the availability before all emails went out, but I never saw it...even up until the point of it loading slowly into not loading at all...very strange.
