Pay for the privilege of reviewing books? Hahahahaahahaha.
Exactly what makes me laugh at this myself. They used to offer free books to reviewers which was a wise policy, it gave the reviewers incentive to actually review them and it was a fair offer; the books were payment for the service of writing a review that promoted the product and by extension Black Library. But paying them for the privilege of reviewing their products, and especially when BL has been just so stellar recently with the terrible AoS novels and producing more so-called Limited Edition novellas than actual normal edition novels/novellas this year.
Well that just makes me chuckle.
