OK, mr. math, so how is it that you still think it's expensive for you? I think it's quite reasonably priced the way I got it online, for what it is. I just think if you want something natural looking, you can't beat coconut fiber and/or reptile bark. Peat moss, at least what I get around here is only slightly cheaper and it's garbage as far as I'm concerned. The coconut fiber is a bit more expensive but a better value. Of course, value is just an opinion. I don't give a damn how cheap peat is, I don't want to use it, tried it, it's crap and so the low cost doesn't matter if it's not what you need or want.

I must have screwed up somewhere, talking about two different substrates. I went back and checked my purchase. It was $4.79 for a 8 (dry) US quart bag (that's roughly 8.8 of your liters) for reptile bark.

Coconut fiber bricks, 3 pack which expand to create 24 liters of substrate, cost me $9.85. (pet store charges around $18) Shipping costs are hardly significant enough to be worth mentioning.

Math gives me headache. I'll let you figure it out. I still think there might be a problem with your currency conversion because, while it's not cheapest substrate I can get, it's certainly not expensive to me. I'm not rich by any means but I still don't think that it was unreasonably priced.
