I find these scrolling through Audibles discounted titles: https://www.audible.com.au/ep/sale?page=1
They are cheaper than a half price credit. Sale prices are available for current Audible Premium Plus members only.
Most of the books didn't interest me; they were the most appealing. However, I suspect a male would be better suited at translating the Illiad, a very testosterone-ny literary work.
The George Orwell Collection is $7: https://www.audible.com.au/pd/The-George-Orwell-Complete-Col…
Crime and Punishment by Dostoevsky (Naxos version) is $6 (I read C&P for a university subject; it was my favourite book from the subject's reading list).
Audible USA seem to have a completely different selection of audio books for sale. The best was Watchers by Dean Koontz, at $7 ( assume that is USD): https://www.audible.com/pd/Watchers-Audiobook/B07D2JG8TH
Are they the original versions, or translations?
