Bumping Mission Doh, I missed the Group Order

And now the lovely labbies have added anniversary goodies. AND extended the Weenies and Sleepy Hollow until the 19th, which is, co-incidentally, the day this order comes down.

Can someone who has done this before help me out with what time GMT I need to order by for it to be before close of business on the 19th by Lab time?  I think it might be midnight, but the original plan was to order by 10.00 pm  because I am going away the next day, and need to be up early, so I shall stick with it!
