Always difficult to second guess a fair price to be honest, so long as both you and the seller are happy with the transaction then it will be a fair price in the end, after all the seller wont sell if he thinks he isnt getting a fair price. Naturally you want to get the Jeans as cheap as possible too, as with anything in sales start as low as you dare and take it from there, but always respect the seller, there is nothing worse than somebody offering a piss take price, its insulting to the seller and the product
