I agree with above comments about having a good piece vs an extra $115 in your pocket....I wouldn't be happy, but I wouldn't refuse/cancel the sale.
Another factor to consider is, what is the true value of safe packaging and arrival of your item? Proper packaging is expensive, materials and time add up - but $195 sounds awfully high to me.
Perhaps you can ask the packaging company to break down the costs for you to shed some light on their charges - then talk to auction company and see if perhaps you can't agree to split the difference about $80 given the miscommunication? Good luck.
