Amazon offers its Prime members National Lampoon's Christmas Vacation on Blu-ray
with free shipping
. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $2.98.) That's tied with our November mention (which required in-store pickup) and the lowest total price we could find now by $2. Sales tax is added where applicable.
Orders placed by December 21 using Prime (or December 18 using Super Saver Shipping) are guaranteed to arrive by Christmas.
