New tour dates announced including one at the HOB Dallas on May 2nd. I hope to get tickets for this show if they don't sell out before I can buy them! Tickets go on sale the 19th of Jan and presale is tomorrow the 18th of Jan.
Your billing depends on your sign-up date and has nothing to do with the date of the announcement.. If you signed up at the beginning of the month when they announce packages, that's when they're going to bill you. If you do choose renew for Vault 35, wait until the third week or so of the month to do it. That way you'll always be auto-billed later in the month of the announcement and will always have time to cancel between the announcement and the payment deadline.
What you said makes sense but apparently the next vault announcement is coming out later at least compared to the last time.
Ticket demand has been so high that the following appeared on the Greta Van Fleet facebook page:
"UK. We are absolutely astounded at the most warm welcome that you have bestowed upon us. Manchester, Birmingham and Glasgow, we are thrilled to announce that the shows have been upgraded to more spacious venues! Tickets available at http://bit.ly/2ATBb0m.
All tickets from original venues will be honored at upgraded venues!"
