Using the same "trick" to add to cart as the Ryzen 7 3800X @ Amazon UK post https://www.ozbargain.com.au/node/550308
Great price for a decent 5700XT (as good as MSI Gaming X, Gigabyte Gaming OC).
$714,38 @ Amazon US
$829,00 @ PCG
Edit: There is the 5700XT XFX THICC III ULTRA option, for $593.67 + 23.35 shipping @ $617.02.
Looks like the Red Devil will be back in stock on July 13th.
