While there might be others threads about Gokano here on TBN, mine actually shows a real proof (bottom of this post) and has more info about restocks/shipping. I believe my thread and my experience could be useful.

Gokano is a new website where you collect points and use them during restocks to get gifts completely for free!

Earning points is extremely easy and not at all time-consuming!

How to collect points (GN):
- Login daily and click the "Collect daily points"
- Complete missions by answering the daily poll (a single easy question)
- Invite new members



Standard members earn 1 point for each of the actions above, while Gold members earn double the points! To receive the Gold rank (and get a free t-shirt along with it) you just need to invite 30 people!

Do NOT cheat to earn points faster, be legit!
Gokano is terminating false/inactive accounts and dishonest members are losing their points.

Prizes:
Gifts are divided in 3 categories: Gadgets, Electronics and Accessories.
Here's a screenshot of some of the Electronics prizes:

Prizes aren't always available, you need to wait for the restocks to order them!

Restocks:
Gokano always announces tha date of restocks, so you know when you'll be able to order your prize. The next restock will be on August 5th!
Since the site is new, so far only two restocks have been held (on June 23rd and June 30th) and gifts stayed available for several hours or days!
I ordered my prize on July 2nd, two days after the start of the restock! See my proof at the bottom of this thread

During restocks, the available prizes will show a green gift icon and a green bar under them.
Here's a screenshot of the order form: Name, Surname and Mobile are automatically filled in, you need to enter the rest of the data, solve the captcha and then click "Order prize now"!


Shipping:
Gokano is based in Poland (Europe) but they ship prizes to any country worldwide completely for free!
Prizes are shipped within 28 working days from order's date.
