I emailed Geocaching support asking if they could give me a free trial to see if it was worth it. They responded like right away giving me a code for a free week trial but it was attached to a year subscription ($40). I subscribed anyways because I guess it's not too bad and I might be able to cancel it if I don't want it.

So far, I will keep it since it unlocked a few geocaches around Cal Poly Pomona and at parks near my area. So for me, it's worth it, especially when it encourages me to to outside and touch some grass.
