If I google the prices, in my native language considering I live in a country sporting reindeers, a large first class pelt can be bought for as cheap as 89 euros, with prices typically going up to something like 150. If it's not treated/processed for indoors/decoration use, the prices start from 50 euros, by the looks of it. Keep in mind that reindeer pelts aren't from 100% wild animals. Finnish, Swedish, and Norwegian northernmost parts are reindeer husbandry regions. The reindeers are only half wild. There are a lot of them! But I suppose it would also depend on where you buy it. Most certainly there ought to be places that rip off tourists.
