The official Green Day store, by Bravado, now has up a vinyl edition of ¡Uno! available for pre-order.
We posted last month about the vinyl for all three albums being available for order from Amazon, which they still are, and with likely cheaper shipping.
The official store only has ¡Uno! listed now $22.98. It doesn't have a release date, but I assume it's the same as the album's release on September 25th.
