Last June 12, I joined a Japanese social network here in Japan. It's Poplle.
It's similar to instagram, but different that you get rewarded 1 yen for every like you make and you also receive 1 yen for every like you get.
It's amazing and fun!
Anyway, today I claimed my first reward of a Choco Monaka Jumbo ice cream. I can claim it from any 7/11 store.
I was choosing between water and ice cream. From hindsight, I should have chosen the former, but my cravings won.
Here's an image of my profile where I got those rewards.
Right now, it's only available here in Japan.
