Page 1 of Amazon offer

A brilliant 4 for 3 offer on amazon at the moment. You can get, for example, the 4-disc edition of Gone With The Wind for 4.97, the 4-disc ed. of Ben Hur for the same price as well as the 3-disc ed. of The Wizard of Oz and, on top of that, you can get an extra one of the same or lower price free. :)
How can you go wrong with an offer like that?
