Prey Deals: 25% Off (Steam) or Free Steelbook (Consoles)
Released just today, you can now scoop up Prey at select retailers with a bonus to boot. No reason to pay full rice at Steam Store or other brick and mortar while missing out on discount or bonuses.
As of writing, the best Prey deal for the PC (Steam copy) is at GamesPlanet for 25% off. The game is discounted to 35 GBP, which converts to about $45 USD, making it a big discount from the original $60 list price. Even better, this Steam key is not region locked, so people in other areas of the world with poor currency conversion rate will be able to reap some savings as well.
Prey (Steam) - $45.37 (list price $60)
Prey (Xbox One/PS4) - $59.99 (free Steelbook cover bonus)
For console gamers, your best bet is at Best Buy which is offering a free Steelbook cover for every purchase of Prey, whether for the Xbox One or PS4. This was original a "pre-order" bonus but it appears Best Buy has plenty of stock and is extending it to anyone else buying the game during release week.
