If anybody is interested in this set then you should probably put in a pre-order for it now. I have noticed that Amazon's prices have been fluctuating a lot.
For example the individual Top Gun: Maverick steelbook at Amazon was $44.99 and then it sold out. It's back again but now it's $48.99.
The Star Trek: Strange New Worlds steelbook was $53.20 at Amazon and now it's up to $57.99. Amazon will probably drop their price soon now that Best Buy has a listing for it at $51.99.
Of course, if you do pre-order this Top Gun 2 pack steelbook set from Amazon and their price drops anytime before release day you'll be charged the lower price even if it goes back up in price
