What Shopify Merchants Should Do For USPS Holiday Shipping Season
Since this USPS holiday shipping price change is a proposal awaiting PRC review, Shopify merchants don’t need to make changes yet, but it’s worth watching closely, since it directly affects Priority Mail, Priority Mail Express, USPS Ground Advantage, and Parcel Select, the services most stores lean on during peak season.
The best way to stay ready is to make sure your rates and label printing update automatically the moment any USPS change goes into effect, rather than tracking it manually during your busiest shipping weeks.

It also helps with managing peak-season volume through bulk label generation, so you can process a high number of holiday orders along with other carriers quickly instead of creating labels one at a time.
