I asked for this for christmas from my immediate family.
$200 = Complete Blu-Ray Set (with special disc packaging for storage) and Ultraviolet copies, Extras all collected in a collectible money barrel
or
~$100 = Six individual packages with the Blu-Rays, Extras...but it looks like only Season 5, Parts 1 and 2 will have Ultraviolet packed in.
I figure if someone else is getting it for me, might as well get the complete set in the special packaging. If you're getting it for yourself, ask yourself if $100 is worth getting Ultraviolet copies on all seasons along with the full blown extras and collectible money barrel.
