We had a crazy good flash sale, and I have over 25,000 orders to fulfill and ship USPS over the next week. Items will go out in poly mailers weighing between 8oz and 1.5lbs each.
Typically, I would ship using Shopify’s postage feature, however, with this kind of volume, I wanted to reach out to get the community’s input on the most cost-effective postage out there.
I know about these options:
- Shopify postage
- SKUlabs plugin
- PirateShip plugin
What plugin/service would you recommend using for a very large volume of orders shipping USPS?
