These are the remastered Ultimate Edition discs WITH a separate DVD with Special Features on for each film.
It's a better deal than the silver box set as that doesn't have the extra discs. Silver box set is on Amazon at the moment for £76.45 as a comparison.
You don't get Quantum of Solace in this box set, but you can pick this up cheap else where if you want the full set.
I ordered it and it turned up in a couple of days.
