I just went back to reread email I received and even though no specific date was mentioned via email, it seems pretty clear to me that people should have sent in a deposit if they have not already...
A few excerpts from the Nov 28th email (I assume it is no big deal to share this and also assume everyone on the list received a similar email)>>>
"As we push closer to production and our waitlist grows larger by the day, we have reached the point in the project where deposits have become necessary to continue."
"requesting a small holding deposit in the amount of $250 USD"
" If you'd like to use a credit/debit card, please let us know in your response and we will let you know as soon as it becomes available, which should be within a short matter of days"
Follow up email a few days later >>>
"Good evening, everyone. We are happy to finally let you all know that we are now set up to accept electronic deposit transfers by PayPal, credit or debit cards. If this is the route you would like to go, please follow the link at the bottom of this message"
There was no specific date mentioned in the emails, but it read very clear to me that if I wanted to stay in, I should send payment...
I agree that a mass email to everyone on the list (With the specific cutoff date) is probably a good thing, but I still think it was abundantly clear that a deposit of $250 should be sent in via check or electronic payment...
