Query: This is a ripoff

I bought this disc and was very happy with it. The Disc covers every FF comic from 1961 to 2004 (575 comics) plus all of the annuals and then 3 weeks later I see Amazon selling the same collection but from 1961 to 2006 plus all of the Annuals plus all of the 185 Silver Surfer comics up to 2006 for $4.00 less. Anybody want to buy a FF collection cheap.
