Congrats! I would love to hear any tips on your pre-select free promo preparations for such a successful promo! 
I haven't run my first select free promo yet, like you, I only have one book out, so I've been hesitant. But I think the opportunity to build an audience and a mailing list of readers would be worth it.
$2.99 is a good price and it gives you leg room for offering discount to $0.99 down the road.
