i could not live without a printer at work and at home.
QVC also offers the QR code return process. no need to print anything out.
What is a USPS or UPS QR code?
No printer? No problem! Instead of printing your label at home, you now have the choice to use a QR code to print your Q Return label through either USPS or your local UPS store. Simply repack the item you’re returning in its original packaging, including the pack slip (if available) or a note with your order number, and cover/remove all original shipping labels on the box or package it arrived in. Then, bring the package return to a return shipping location, where they’ll scan your QR code and print the label for you.
