Most, if not all, are repeat deals so check your files before buying. (Note that if the ASIN remains the same Amazon will say you've already got it but if it's changed they'll happily take your money again.)

At least 3 are repeat deals (that I know of) so check previous purchases.
You'll need to scroll past the freebies (but the first item is the Gollancz Festival 2019 sampler). At 99p there's several titles by Brandon Sanderson, book 2 of Shattered Sands, a Tom Lloyd and various novellas & short stories (Joe Hill and Robert E Howard). At £1.99 there's more.
