Christmas Shipping
Bustards don't employ magic dwarves or LSD fuelled reindeer so have to rely on good old fashioned planes, trains and automobiles.
So if you want your stuff before Christmas we'd recommend ordering before these dates.
USA - 10 December
Europe - 13 December
UK - 19 December
Anywhere else. Good luck, its in the hands of whatever god you worship (including Mars as that's down to Elon).
