There are a number of Tabletop RPG Bundles available at Humble Bundle at the moment, and I will list them below. It should be noted that you can gift Humble Bundles (I was gifted a bundle a number of years ago) and said bundles can make for nice gifts for the gamemaster in your life (if you wish to steer them towards a new system - hint, hint) or inexpensive gifts (at the lower price points) for the players in your group.
It should be noted, that if you use any of the links below, they are affiliate links that will go to support The Tavern. If that makes you uncomfortable, you can always go directly to the Humble Bundle site and avoid the affiliate links completely. The choice is yours.
In no particular order, the Tabletop RPG Bundles are:
Cyberpunk by R. Talsorian - If you are looking for Cyberpunk 2020 you'll likely be well covered. You can even get the Cyberpunk Red Jumpstart Kit. 18 bucks get you 30 releases, and as always you can scale down to pay less.
Digital Dungeon Maps, Tokens, & Assets featuring Alyssa Faden - a true smorgasbord of gaming resources. Alyssa's attention to detail in her maps is second to none.
Pathfinder Second Edition Beginner's Bundle - one of the best values in tabletop RPGs was the Pathfinder First Edition Beginner Box. It was a version of Pathfinder I would be willing to play, but the value of the included pogs/tokens is second to none. The PF2 Beginner Box ALSO has the pogs/tokens (I own it - my only PF2 purchase - can't speak for the rules but the contents give value for money). This bundle gives the option of receiving a physical Pathfinder Second Edition Beginner's Box. There is also a Fantasy Grounds Pathfinder First Edition Ultimate GM Kit Bundle available. (edit - I initially mislabeled this for 2e)
Star Trek Adventures by Modiphius - I should pick this bundle up just to see Gareth Skarka's pen name in print ;)
