The Egmont owned website DinTidning.se is the go to place for Fantomen subscriptions and they have just added a new piece of merch for the new subscribers.
This tote bag is added as a free extra when you start a new subscription of 4 or 8 issues of Fantomen. At the time of this article published (14 January 2023) they have a special of up to 50% off for partial subscriptions.
The partial subscriptions is great if you want to test a subscription before committing to a yearly subscription.
I have earlier used these kind of offers while having an ongoing subscription and got the new issues to be added on back of my current subscription. I would suggest contacting DinTidning website support to be on the safe side regarding this though.
