In honor of Mother's Day, get $2 worth of MP3 credits at Amazon via code MOMROCKS with no purchase required. Go here and click on the yellow button that says "Enter Your Code" (if you're not already signed in, you'll be prompted to do so). A popup box will appear that says "Redeem Your Amazon.com Gift Card or Promotional Code," and you'll type or paste the code in the box under "Enter a New Code." After you click on "apply" it will say "Success! Your Amazon gift card or promotional code has been applied." The $2 credit will appear in your account and will remain there until redeemed for MP3's or until it expires on 4/22. Note that this offer can only be used once per account. If your mom is anything like mine, she doesn't know how to use MP3's, so be a doll and buy some songs she likes and burn a Mom Mix for her.
