While shipping carriers traditionally adjusted their rates annually, additional changes may now occur throughout the year. These adjustments don't necessarily affect every shipping service, so you may notice changes to some rates while others remain the same.

These adjustments aren't unique to USPS® and UPS® and can happen with any shipping carrier. Pirate Ship never charges fees or markups on top of the deepest discounts available, so you'll always have access to the deepest possible USPS discounts and discounted UPS rates.

We're unable to predict these changes and neither should you! One easy way to quickly determine what your shipping costs will look like is to plug your info into Pirate Ship's Rates Calculator.
