In Sweden you can either use bank transfer, invoice (provided by Klarna), and I do not think accepting credit card payments is hard either.
Almost no Swedish businesses who target the Swedish market use Paypal. Paypal is mostly use by Swedish companies when they want to target any country in the world (for example Minecraft).
Dealing with the Swedish credit card providers isn't really any nicer than dealing with PayPal, but it feel better to be dealing with a local company in case something goes wrong.
In Europe bank transfers solve the person-person transfers so there's no need for PayPal for those situations, but for small fry accepting credit card payments it's hard to beat.
