Here you can purchase an electronic gift card.
You get an attachment which you can print out. It’s also possible to just forward this e-mail to whomever you want to give it to.
For an extra cost of NOK 100 we can send you a physical gift card in your mail (Norway only), which you can then give to your gift recipient. Feel free to enter a custom amount. The gift card is valid for 2 years. Any amount left after booking can be used in the restaurant on the island.
