They're doing well. Exceptionally. Magnificently. In the few days following the 69-year-old's death, Amazon.com has become "temporarily out of stock" (sold out) of CD and vinyl editions of the brand new Blackstar LP, which is likely to become Bowie's first No. 1 album on the Billboard 200, 49 years after his self-titled debut dropped.
As of this publishing, Amazon is also completely out of stock of every single other David Bowie studio album—of which there are twenty-freaking-five. The 2013 10-years-in-the-making comeback record The Next Day says it will be available Jan. 19. Most or all of the CDs and vinyl editions are available from independent/third-party sellers that do business on Amazon.
On a more serious note, the company has been accused by multiple sources of jacking up its prices since news of Bowie's death broke early Monday morning. Fuse has reached out to Amazon for comment. The company has algorithms to adjust its prices based on factors like supply and demand, as articles from the Wall Street Journal, Retailwire and Camelytics—a blog that "analyzes pricing data from Amazon other retailers"—have explained in the past. It's unclear if that's the story here.
The following tweet allegedly shows screenshots from Sunday, Jan. 10—the day before we learned of the artist's death—and Tuesday, Jan. 12. We'll definitely allow for the possibility that it's Photoshopped:
