I'm unsure how long the sale will go for, but some people have said 21/Nov.
Criterion Collection DVD's are normally very very expensive, but are well worth it for their quality of transfer and content.
They held a sale like this only several months ago, but in past you would have been lucky to get two such sales in the same year.
edit: BluRays are region locked, so I took them off the title… they're going for ~$20US - not compatible with aussie players. (thx for the reminder in the comments)
Shipping starts at $8.50 USD, ($7.50 per order, $1 per item)
Lucky for me my player is region free :) I purchased 4 Criterion Blus the other day using this link

Doing it through that link gave me an extra %10 off the sale price. Hopefully it will work for you too
this finishes this week and they also have 50% for blu rays as well as dvds. bought 4 last night. pity that the third man is OOP.
just need to buy a region free blu ray player!
Just a warning I know the blurays are region A locked. You will need a region unlocked player to view them. If I had a region free player I would be buying quite a few of these movies.
