HUGE savings on the Necron Flayed One and Adepta Sororitas Battle Sister McFarlane figures through Mighty Ape's Amazon store (and on mighty ape itself). I only ever buy the artist proof ones and paint them myself, personally, because the paint jobs on the pre-painted ones look like absolute arse.
Adepta Sororitas Artist Proof $10 - https://www.mightyape.com.au/product/warhammer-40k-adepta-so…
Necron Flayed One Artist Proof $15 - https://www.mightyape.com.au/product/warhammer-40k-necron-fl…
Adepta Sororitas Battle Sister (Black armour) $15 - https://www.mightyape.com.au/product/warhammer-40k-adepta-so…
Necron Flayed One $15 - https://www.mightyape.com.au/product/warhammer-40k-necron-fl…

Also available on the Mighty Ape Amazon AU page, if you more inclined to use Amazon, though these are not eligible for free post.
Thanks OP, one very happy camper in my house now 😀
