Its in my signatureYou might want to say where your vendor is located at.
Also, barbed is the best, however it is also the "easiest" to acquire. Who goes farming spined leather? So it can cost more, supply/demand. If people have BODs for spined leather they might just rather buy it than go farm it.
Spined is required for decent BODS, but harder to acquire because... you kill a dragon, you get 25 barbed, which is almost enough for a barbed set. That means that from kiling a dragon, you get a 1k-1k5 gold bonus just from the skin.
Spined is looted from giant serpents and ratmen, things like that, and drops in much lower quantities. l'd pay for spined but I'd never pay for barbed.
True.. but you can kill several ratmen in the same amount of time it takes you to kill 1 Dragon.. Also.. Since barracoon is the most frequently done champ.. You can literally farm 1000's of Spined leather, without ever even having to kill a single ratman. Each ratman gives 8 Spined Leather. Lizardmen also give spined leather.. Spined is by far the easiest to acquire. Spined leather is easier to farm than regular leather even.. Since there is areas that continually spawn shit loads of mobs that drop spined.
All that being said.. People, myself included, are just too lazy to farm their own.. but I will hold off at that price..
