The Amazon MP3 Store offers downloads of Queen's Greatest Hits MP3 Album for $2.99. That's a buck under our March mention and the lowest price we've seen for this 17-track, DRM-free classic rock album, originally released in 1992. (iTunes charges $11.99; Google Play charges $11.49.) Amazon MP3 Downloader is required.

Of note, you can claim a $2 Amazon MP3 Store Credit via coupon code "HEARTMP3". If you've not already used it, it's valid with the above offer, which brings the price down to 99 cents.
