Buy an MP3 Album, Upgrade to 20 GB of Cloud Drive Storage
Here's how to qualify for this offer:
Purchase an MP3 album from the Amazon MP3 Store by 11:59 PM PST on December 31, 2011.
If you qualify for this offer and either have not signed up for Amazon Cloud Drive or have the 5GB Amazon Cloud Drive plan, you will be automatically eligible for the 20 GB plan for one year from the date of your MP3 album purchase. Unless you set your account to auto-renew to a paid plan, the 20 GB plan will revert to a free plan one year from the date of your MP3 album purchase.
If your Amazon Cloud Drive account is already at 20 GB or higher when you qualify for this offer, the offer will be saved to your account as a $20 credit toward any future Amazon Cloud Drive plan fees you may incur at the time your plan renews or at the time you upgrade your plan. If you elect to downgrade your plan to a free plan at the time of renewal, your upgrade offer will be applied towards the 20 GB plan at that time.
