I think the main benefit is your orders get higher priority during holiday season when it's busy and regular orders may take a long time to fulfill.

You're likely right it does put you in a higher tier of priority, however how that plays out practically be a relatively slim advantage or speed increase - as is my and OP's comments allude to. Comes back to the rule of efficiency and lower cost with adequate planning, planning ahead of time, detriment of impulse or last minute buying, and stability of supply-demand systems.
