If you’ve somehow missed out on playing the Portal series so far, now’s the time to buy it. The popular game is today available on Steam for 75% off it’s retail price. That comes down to only $4.99. 

The deal also applies to a couple other Portal options. You can get the two-pack where you get two copies of Portal 2 for only $8.74, normally priced at just under $35. A Portal Bundle that comes with both Portal 2 and the original Portal is only $6.24, an incredible value in itself. The last thing on sale with this deal is a digital book for Portal 2 called The Final Hours which is only $0.49. Are you going to take advantage of these awesome deals?
