This weekend, Steam is offering gamers a way to save money and support indie game developers at the same time. They're offering a bundle of five different indie games at 80% off their normal price.

The game's included in the "Greatest Indie Pack" are Eets, Gravitron 2, I-Fluid, Multiwinia, and Trials 2 Second Edition. Normally buying all five games would cost you $44.95. However, if you pick them up between now and Sunday, you can get all of them for only $9.99.

Wondering why Steam and other services like Good Old Games have special discounts every weekend? While speaking at the DICE summit this week, Valve's founder Gabe Newell revealed that a 75% sale on Steam results in roughly a 1470% percent increase in sales. That huge of a spike in sales is more than able to compensate for the lowered prices.
