That's a pretty accurate account of what occurred. It's widely accepted that the first person to post "I'll take it" gets it. That's normally followed by a PM with details. When transactions are posted as such, it's transparent and there is no doubt about who's first, second, etc. When business isn't conducted that way, there's no transparency and questions quickly arise. I posted "I'll take it" first. There's a record of that on the thread. It should have been mine, no questions asked. That was my experience.

Deadlines and commitments, what to leave in, what to leave out...
