What This Means for WooCommerce Stores
The impact of a USPS holiday rate increase depends on how your WooCommerce store calculates and shipping charges. Stores using fixed shipping prices may need to review their rates if the proposal is approved. Stores that absorb shipping costs through free shipping may also see their margins affected.
The impact can be greater for merchants that:
- Ship high volumes during the holiday season.
- Frequently use Priority Mail or Ground Advantage.
- Ship heavier packages.
- Ship across longer zones.
- Use USPS Flat Rate services.
