Dear Amazon Web Services developers,
 
We’re excited to announce a new feature that makes it easy and cost-effective to broadly share data stored in Amazon S3.  This will enable you to provide other developers access to your buckets without incurring their access costs, and even use Amazon Web Services to sell data for a profit.

You can now configure an Amazon S3 bucket to bill the requester, rather than you (the bucket owner), for both request and bandwidth fees associated with access to the bucket.  Requests against such buckets must be authenticated and bear a header that signifies consent to be billed for the request.  Bandwidth between EC2 and S3 within a region remains free of charge when this option is enabled.
 
Used in conjunction with Amazon DevPay , the new “Requester Pays” option also enables selling access to data stored in Amazon S3 either as a subscription or by marking up individual request fees. 
 
Guidance on getting started:
 - Using Amazon S3 “Requester Pays” Option
 - Using Amazon S3 “Requester Pays” with Amazon DevPay

Thanks,
The Amazon S3 Team
