Because I like to test things out, here are the results:
+$5 Switch game promo is still active and just needs to be $2+ TIV
+$5 PS4/XB1 only applies to games over $5 TIV as described
You can't pre-order FFXVI or God of War Next, so you need to put at least $5 down on whatever PS5 game is in the system.
Manager said all the GS in the area sold-out of PS5s yesterday, with a "NO PS5 AVAILABLE FOR PREORDER" sign right on the door.
Thanks for posting this, my local family video is closing soon so all there games are marked down, just stocked up recently on a handful and this promo will help with just preordering my PS5 yesterday.
