My beloved fellow indie authors, if you do a scheduled price drop (especially through a third-party aggregator), be sure to check Amazon listings after the sale ends.
For some reason (greed or slopcode, who knows?) Amazon may refuse to list your book at its proper price afterward.
This has been an intermittent problem for months, growing steadily worse. Not even Bookwire (Ingram) can get a straight answer out of Amazon—in some cases, the ‘Zon (if responding at all) flat-out and demonstrably lies saying it’s price-matching to a different distribution platform.
