I thought with new social measures that it was quite hard for the online companies to keep up to demand in their warehouse whilst keeping to government advice and social distancing, which is causing a lot of stock to die because they don't have the hands to move it.
So, you need to get in the online queue at the right time. This could be either 2:05 (order before 2 for next working day) so if you order after two, you'll be in the following NWD's orders. Or the time could be early hours of the morning, or it could be 9am.
Good luck.
