Why would you think shippings costs now would remain the same as in the 90's?
Should I craft a doctorial thesis on the topic for you?
I wasn't suggesting that the shippings costs would be the same. But compared to the price of the thing being sold, the fees and shipping have disproportionally skyrocketed. For example: A Mexican P bass in the late 90's would sell for about $500-$700. Today, the same bass sells for about $600-$1000. About a ~30% increase in value. Meanwhile fees and shipping have more than doubled.
Whether or not that clears things up for you, have a good day.
