Here’s my email reply:
Hi (first name), good news & bad news.
The bad news is that you were not one of the first 20…
The GOOD news is that in order to confirm your spot we require your payment information, since it’s only a one-time fee of $47 (debit/credit card number with exp date).
And so far only 18 out of the first 20 confirmed by sending me their cc info.
I don’t want to wait too long so if you want to get this $47 deal just email your payment info and I’ll squeeze you in =).
Also let me know what day & time you can start!
I attached a picture of my gmail inbox just so you know I’m not making this stuff up :)
Talk to you soon,
Michael “The Engineer” Duivis
