Buy an album from Sony Music's bandit.fm music service using a credit card and get $20 credit free.
To participate in the offer, you must purchase an album on the bandit.fm site with your credit card within the promotional period. The promotional period is 1 September 2009 to 30 September 2009 (inclusive), unless shortened by Sony Music in its discretion.
The offer only applies to your first purchase of an album with a credit card during the promotional period. Any subsequent purchases do not attract the $20 credit.
You must use the $20 credit amount within 30 days of receipt, after which it will expire.
The offer does not apply if you have existing credit on your account from recurring top-up credit, gift certificates, bandit.fm cards, promotional cards or any other voucher credit (Voucher Credit). Any existing Voucher Credit must be expended before you are able to participate in the offer.
Here's what I just did: firstly, I signed up for an account and redeemed the $20 free credit from this previous offer.
I then bought two albums ($11 + $16). I didn't have sufficient free credit for the second album, so I entered my credit card details. I used free credit + credit card to buy the second album and received another $20 free, as detailed above. Now I can get a third album free and have a little bit of credit left over.
I therefore got $40 of music for around ~$7 — not a bad deal!
