I think there's some deluxe version left at https://www.amazon.co.uk/gp/product/B06XSKTG6V/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 . I don't know if you can order to US from there but anyways. I ordered mine from amazon as a gamble and I'm hoping its the artbook version since the supposedly the deluxe vinyl are supposed to come housed IN the artbook and there isn't any separate deluxe version apart from the artbook one in gorillaz.com.
I just checked amazon US and there are still some deluxe editions available for pre-order:
The German Amazon shop still has the Vinyl + art book. Check it out
Try this one: https://www.amazon.ca/gp/product/B06XSKTG6V/ref=ox_sc_act_title_1?smid=A3DWYIK6Y9EEQB&psc=1
If that doesn't work, its listed under the list of retailers, seller listed as Amazon.ca: https://www.amazon.ca/gp/offer-listing/B06XSKTG6V/ref=dp_olp_new?ie=UTF8&condition=new
Looks like amazon uk must have sold out today... German Amazon has it available it seems.
Here you go, but it's not available.
Amazon has pre-orders up for both Deluxe Artbook as well as Standard.
Same goes for Bullmoose.
Gorillaz.com also has pre-orders (but they say they are sold out of deluxe).
(Amazon & Bullmoose do not charge until item is actually in stock fyi.)
Here it is on Amazon UK: https://www.amazon.co.uk/dp/B06XSKTG6V
