The following games were reduced in price for a pre black friday sale. There is also a B3G1 free preowned games that it can be combined with.
Fire Emblem: Three Houses
Mario Tennis Aces
Mario and Sonic at the Olympics Games Tokyo 2020
Yoshi's Crafted World
Each at $27.99 pre-owned, makes $84.97 for 4 games using B3G1 promo. You can get one of each or multiples of some for gifts.
My opinion: Fire Emblem is an amazing game, worth buying even at retail. Mario Tennis is also a good game for multiplayer. I personally didn't like Yoshi's Crafted World as an adult but it seems good for younger audiences, with the ability for 2 players. I have not played Mario & Sonic Olympics Tokyo 2020 but heard it has bad reviews, at this price I am willing to give it a try.
There are other discounted $27.99 games that you could also replace some of these with too.
