After several hours looking for something, I finally managed to find this forum via google and located what I was looking for here:
http://www.wickedfire.com/sell-buy-trade/63593-fresh-gmails-accounts-10-1k.html
Little did I know this would not be the end of my journy...
I then registered and verified an account so I could send a message to the seller to express my interest in purchasing from him.
I was then told that I am unable to send a PM until I had made at least one post.
Thinking 'that's fine, I'll just post in the thread that I'm interested, then send him a message', I tried doing just that, only to find that because it was over 103 days old, I can't reply (uh-huh...).
This then left me having to find another thread to make an aimless post in to be able to send the seller a message to buy what I was after.
Including search time, this means that my $10 item is actually a 2 hour and $10 item. Since this is atually for my work, and I am doing this rather than client-billiable work, I guess that means that it has cost my work $160 (2x hrs billable at $75/hour + $10) for some Google Accounts.
Oh, and to top it off, my car was stolen today. That's not overly relevent to the task at hand, but another factor adding to my somewhat unpleasant mood.
So... now that I have made my initial post, I guess it's time I try again to message the seller again.
