It's the most wonderful time of the year, indeed. The great sales on video games continue on Amazon as the online retailer has discounted the BioShock Triple Pack by 81%.
Available for $14.99 — roughly $65 cheaper than its list price — the Triple Pack includes all three games in the series. Yes, even BioShock Infinite, which sells for $19.99 (with a discount) on its own, is included. It really is the best option right now if you haven't yet started the series.
Alternatively, you can purchase each game separately since they are all discounted currently, but that method doesn't make sense as the Triple Pack is ridiculously cheap right now. It should be noted that this deal is only for the PC digital versions of each game. The sale ends on December 3rd at 11:59pm PST.
