Pro Bundles
Humble Bundle offers bundles of games for pay what you want pricing. These happen quite often with indie bundles, publisher bundles as well as weekly bundles. There are different tiers to the bundles that go higher in price depending on how many games one wants from the bundle. The higher tiers have a higher price floor but still offer considerable discounts on games. All bundles payments can be put towards a charity for that bundle as well as towards the developer or the HB themselves.
Pro Have a say where your money goes
Able to put all the money towards charity, the developer, or Humble Bundle.
Pro Pay what you want
The way Humble Bundle works is that it is donation based in that you can pay what you want for the bundle, with the minimum being a dollar. There are separate packages in each bundle that also ask for a minimum price, which depends on the "beat the average" price which is what on average has been donated so far..
