April is Amazon Web Service's Amazon Simple Storage Service (Amazon S3)'s third anniversary. In honor of this, Amazon is offering S3 data transfer in for $0.03 per GB (vs the normal $0.10) from April to June. This is a welcome announcement for those of us using S3 storage for files.
Check out our SlickUpload with Amazon S3 example for more details on using SlickUpload to upload to S3.
