It looks like there is a new $2.00 credit to use toward MP3s from Amazon.
The $2 credit expires 7/11 .
I am not sure how long the credit will be offered so be sure to hurry over and grab it while you can.
I just tested this and got (3) of the $.25 Summer Jam songs and it worked perfectly for me.
Head over here to Amazon and click the yellow box that says “enter your code.”
Enter HEARTMP3 and you should see the $2.00 applied to your account.
