You have to pay to return the set to the mint for exchange or refund. As long as it is an annual set of some sort you can use an inexpensive shipping method at the post office. You might be able to get the mint (PBGS) to refund your shipping charges if you call them and explain that you are returning for replacement because of significant quality issues. Which set did you buy and how significant is the spot? Remember that when a single coin in a multi coin set is defective, you have to return the entire set (not necessarily the entire order), you cannot send back part of an item purchased.
