Can be worth picking up Beat Saber, it's still one of the best VR games in my opinion even though it doesn't go on sale.
H3 is good but only if you like guns, there's barely any game there beyond the firearms simulation.
I'm also a huge fan of Into The Radius but I'm also a stalkerfag, it's pretty janky but it's also a complete experience and there's nothing else quite like it at the moment. 
VRChat and The Lab are both free and can be neat introductions to VR. 
There's other games like Boneworks, Pistol Whip, and Walking Dead SS but I'm not sure whether they're on sale.
