Collect them all!
Humble Bundle’s Summer Sale is on. And that means good deals on all sorts of games. But it also means Summer Sale missions. All you have to do is log in and go to their store page once a day to get stamps. Once you collect enough, you get some freebies! Here’s what you can earn with those stamps:
1 Stamp:
10% discount coupon for Humble Monthly
2 Stamps:
15% discount coupon for Phantom Doctrine
3 Stamps:
Receive Braveland for FREE!
5 Stamps+:
Receive The Ship: Murder Party for FREE!
There’s a lot to gain from logging in to Humble Bundle’s store every day. And you’ll want to: the stamp promotion ends on September 6th at 10am PDT, and your stamps don’t carry over to the next promotion.
