Well, since no mods censored me for posting last time, thought I'd share again...
This is completely free, just redeem the code "GET3MP3S" on US Amazon's
Get $3 in MP3 Downloads page and you'll get an instant $3.00 credit in your account. The catch is that you have to spend that amount before November 29, 2010 11:59 PM PST and you can only use it to get MP3s.
* I used this code with Amazon's
Black Friday Deals Week for MP3 page since they have several albums there priced at $3.99 including Kanye West's My Beautiful Dark Twisted Fantasy album, etc.
