So, Swedes have a bunch of probably very strange habits, but this one, I think most of you would love.
Every year at the end of February, since 1940 there is a national book sale. Like EVERYWHERE. Every book store has this huge sale with books piled high as far as you can see, and it applies to their e-book sales too (om nom nom nom!). Grocery stores push aside aisles to put out enormous tables full of cheap books. I've even seen great big baskets of books set out in IKEA and clothes stores and you name it. The MacDonald's happy meal toy at this time of year is often a kids book instead (although, it's a few years since my kids were getting happy meals, I once got a beautifully illustrated hardback version of Selma Lagerlöf's "The Changeling" from one. Well, my daughter did, technically, but I loved it more than she did).
It's a really good sale too, sometimes as high as 70% off new releases, or buy 1 get 2 free deals. And it's all genres, you can as likely find highbrow coffee table books that normally cost a fortune, as well as 10 for 100kr YA romance packs. A lot of stores do mystery packs, and just bundle up 2-3 books already wrapped, for a set price, and those are quite fun. But mostly, it's any book you can think of, for really cheap.
Swedes love to read, and love to share books, I often take a bus that has a "take one, leave one" book basket in, and it's always full to brimming over. I've gotten some great reads out of there! You'll find the same thing in coffee shops and restaurants catering to the lunchtime trade. In a coffee shop, you're more likely to see 20 people buried in a book than with laptops, like I'm used to seeing in other countries. But the book sale is above and beyond, and I think it's really cool and a bit special.
