For those under the impression steam has the best discounts please use isthereanydeals before buying games so you don't pay more than you need to.

Recent example is ARC Raiders. https://isthereanydeal.com/game/arc-raiders/info/

Current best price is 15% off for $34.17 versus $39.99 on Steam. And all time low was $31.92.

Don't assume because a game is for example $39.99 on Steam that it is the lowest prices and paying more for the exact same game tied to the same launcher. Search before buying.
