Hi all,
Saw this pop up in an email this morning, $79 for PS5 Valhalla down from $99.95. Amazon are usually pretty good with updating pricing as well so it's possible that it will drop and you'll be reimbursed the difference through their pre-order guarantee.
I couldn't get in on the Amazon PS5 deal (Zip delayed until OOS) but at least I can get in on a decent game deal for a first play on the new system.
Next cheapest I saw was $86 excl shipping from ozGameShop, happy to be proven wrong though.
Pretty amusing that they're charging an extra $10 compared to the PS4 version, when Xbox owners get a free upgrade.
