Get both games free for the first 24 hours after their release on your android device through Amazon's Android store.
"Bejeweled developer PopCap Games has signed an agreement with Amazon, noting that it will release its first two Android games exclusively on the Amazon Appstore in two-week slots.
From tomorrow, Chuzzle will be available solely from Amazon's Android store, up until May 30. Tower defense classic Plants vs Zombies will also get an Android release later this month, again exclusively via the Amazon Appstore for two weeks.
Both games will be completely free to download for the first 24 hours after release, and subsequently be given a list price of $2.99. After the exclusive periods, the games will then be available via the regular Android Marketplace." -Gamasutra.com
