With the soft launch done, the next step was a real test order. I ordered the product to ship to my house in Shopify. I did the online process, and everything went great, including the payment processing. I released the order in Printful, and it sent an automatic email notification. After a few days, I got an update that the order had shipped.
While awaiting delivery, I researched and figured out how to pay sales tax to my state Department of Revenue.
I signed up to get shipping tracking. The United States Postal Service was delivering it. I got frequent updates. Finally, it arrived at my house. The packaging was great for protecting the mug, and the mug looked great with the Star Atlas logo.
