There was a period when Amazon sporadically charged on pre-order, instead of the usual dispatch. Also happened to me on a few orders. I don’t remember if it was deliberately or an error but anyway after a short period this stopped happening and now it’s charge on dispatch only.
Shipped very well protected, even double boxed. I think the set comes inside a cardbord box straight from Criterion, then Amazon had put that inside another cardboard box. Can’t complain about the packaging at all.
