DubConqueror: Does Steam have a notify at price drop option? Gamersgate does, but I haven't managed to find out how to turn that option on on steam.
Every now and then I get an email from Steam when a game in my wishlist is on sale. I don't remember any setting about it, so I guess it's automatic.
Edit: Yep,
here it is:
We'll let you know by email or through our mobile app when the games on your Wishlist are on sale as a Daily Deal, Midweek Madness or Weekend Deal. Whether you're riding the bus, walking the dog, or stuck in a meeting, you'll know when there's a deal!
If you'd prefer not to be notified, it's easy to opt out of email or turn off mobile notifications.
So, it should be automatic and you have to option to turn notifications off.
