I just realized why I hadn't had anybody place any pre-orders; I hadn't set any prices! Sorry...
$14.00 each for orders received before the print order is placed, includes shipping to US addresses ($4.00 extra for international orders). After the print order is placed, the price will be $18.00 each ($4.00 extra for international orders).
Payments can be sent via PayPal to david.g.thornton at gmail.com. I'm also set up to use Apple Pay, and am working on Venmo... Let me know if you'd prefer to use one of those methods and I'll get you what you need. Also, if there are any other payment methods that would work for this, especially for buyers outside the US, please let me know.
I'm planning to have it print-ready early in the week of Thanksgiving; should have them in-hand to start mailing them out the first week of December.
I've received some amazing photos from 28 people this year! I'm still working on figuring out which ones to use; not an easy task because I like so many of them. And my apologies if you sent something and I haven't yet responded to you; I'm getting there! Many, many thanks!
