Amazon is offering a free $2 Amazon MP3 Credit with the code HEARTMP3.
Click the enter code button on the site to use.
This is different from the old offers as it is not expired and has a new code.
Terms and Conditions:
Click the button below, enter your AmazonLocal voucher code, and click the "Apply" button.
Once you receive confirmation that your code has been successfully entered, a $3 MP3 credit good toward any song or album in the MP3 store will be automatically applied to your Amazon account and your MP3 promotional balance will increase by $3. If you receive an error entering your code, be sure to check that you've entered the code correctly and be sure that the promotion is still valid and has not expired. If you still receive an error, contact Customer Service via Amazon MP3 Support.
Find the song or album you want and buy it with 1-Click. The visible price of your selected MP3 song or album will not change but the $3.00 credit will be automatically applied to your order. This credit cannot be combined with the "HEARTMP3" promotional credit.
After your purchase, you can confirm that your code was applied by either viewing your order details on the purchase confirmation page or checking your order confirmation, which will be sent to you by e-mail.
Amazon MP3 music is available to customers located and with billing addresses in the United States. You must have an Amazon.com account and accept the Amazon MP3 Service Terms of Use to redeem the code. Limit one per customer.
You must redeem your credit by 11:59 pm PST on July 11, 2012.
Additional Terms and Conditions apply.
Note: The code is for the Heartmp3 promotion and not the Amazonlocal $3 promotion.
So you need to change your Amazon billing address to one located in the United States? I presume that you also need to be using a service such as unblock-us, so that the website thinks that you are in the United States? Sounds like a lot of effort for a $2 credit.
