I'm not so sure that Wal-Mart will be able to beat that one, $14.95 is a killer deal. Plus if you need batteries for your remotes, you get another $4.00 of with the purchase of 2 packs of Rayovac batteries.
There is some other differences between the two. Like you said, the 50 minute documentary is missing from the 2-disc set to fit the 1982 version of the movie. But also exclusive to the Gift set is an 18 minute documentary "Creating E.T." and a short 10 minute discussion with John Williams, "The Music Of "E.T." - A Discussion With John Williams".
