Depends on what thickness you need? :-/
But I assume you're looking for 45x145 mm: 16.45 SEK/lpm
or 45x195 mm: 23.95 SEK/lpm. The prices are from:

Ok. Yes, I have found these prices before, but I thought there was a difference between this timber and what is required for use in load-bearing constructions.
What is meant by the different 'K-classes' for timber? I thought that some level of 'K-timber' was required for example for load-bearing exterior walls. Or is it that the timber you are linking to is suitable and approved for building exterior walls anyway?

As far as I understand, walls are normally not critical in terms of strength, as long as you are not planning to build a high-rise. Or have some more exotic load cases (such as transferring the entire roof load onto a single column or similar). Normally, the dimension of the wall construction is more determined by the insulation thickness than by the load. However, there may be quality requirements for lintels over windows and doors sometimes. But this should be covered by the person who makes the construction drawings.
Exactly, K-timber Construction timber must be clearly indicated in the construction drawing! As mentioned, it is mostly found in trusses, joists, and reinforcements, etc.
Only K24 belongs on the top chord and then on your own initiative:

I can mention that there were pictures in another thread here quite a while ago of wall sections from some prefab manufacturer. There, the studs in the exterior walls were made of 2 thin studs (looked like 45X45) that were placed about 200mm apart, with insulation in between. A way to avoid thermal bridges. And if you can do it semi-automatically in a factory, it's probably cheaper with 2 joined 45X45 than one 220X45. Though it did look a bit flimsy.
Yes, I've seen something similar. I think it was on a website for a company that sold 'lätt-reglar'. These consisted of two thin studs with a piece of hardboard in between. Positive in terms of weight and thermal bridging, but as I understood it, it became a bit 'puligt' with the insulation because standard width/sheets no longer fit...
Currently, it looks like I will build with regular lumber and then place horizontal 45x45 inside to reduce thermal bridges.
