And to celebrate the grand opening, they are giving away Airport Mania: First Flight for free until June 1!
Many of the titles are available on the Mac App Store at the same prices, however it appears Amazon has the EA games unavailable on the Mac App Store. Otherwise, the selection is very small for now.
Currently there is a coupon deal for $5 off one purchase which might be worthwhile if you were looking for a discount on the available Mac games in digital form:
Celebrate our new Mac downloads stores and save $5 on any Mac game or software product through June 1, 2011. To save, click the "Buy and download" button on the product you have chosen, then enter the code SAVE5MAC in the "Gift Cards and Promotions" box. Limit 1 discount per customer.
I left the thread as a wiki in case Amazon does Mac gaming deals more regularly in the future.
Update June 1: Big Kahuna Reef for free
