Book Grocer have just put together a new Fantasy book box, with an original RRP of approx. $400. There's a full book list available when you click the link, and it works out to be $5 per novel.
They also have other boxes on the site, sorted by various genres/themes, and all are heavily discounted from their RRP.
All the boxes ship for free Australia-wide, from Melbourne (making this pretty perfect for fellow Victorians stuck with time on their hands during this lockdown).
Let me know if you have any questions, I'm associated with the store and can do my best to help!
Most of these books are not worth reading. Do you have any boxes with decent books? I appreciate the low price but no one wants to spend 100 on mediocre stuff.
