Amazon.com is offering $2 in free MP3 downloads with the code GIVEMP3S. No purchase required. See details at this link. It should increase your gift card balance by $2 for music purchases only. You must redeem the code soon – by December 26, 2010 11:59 PM PST. Limit one Amazon MP3 promotional credit per customer.
It may ask you to install the AmazonMP3 Downloader software, but you should be able to skip it for individual songs. Entire album purchases may require installation. I gave in and just installed it, it seems to work fine with iTunes.
Update: Bing is offering up another $1.29 in MP3 credit. Just enter your e-mail and enter the code you get in the same place as above.
Updated post to add another $1.29 in free Amazon MP3 credit. Which version of Jingle bells should I buy?
Sweet! Thanks for the share. I love me some free music.
