Is that for the super special edition? Lately there seem to be 3 different versions of each disc available on day one. The one disc version in either full or widescreen. This generally is on sale for around $14.99 the first few days. Then there is the 2 disc special edition that is over $20. Not sure if this is the case for GOF, but that's the way Batman Begins, Chocolate factory & Walk the Line have been (just naming three that I've picked up in the last few months).
What would be really nice is if they provided a 16-hour Director's/Writer's/Author's cut.
Or at least re-release these with the deleted scenes actually in the film, as opposed to plopping them together at the end. I was thinking they should do this once all seven are out. Rerelease them as a set with the deleted scenes included within the body of each film.
