@just wonder I have never been able to search all my past orders on QVC. And, my searches don't always reveal the same past purchases. It's not like A.... where you can look back by year or name of item.
In order status, search "view all", it should let you go back, on an iPhone, look down at the bottom of your phone. and it'll let you scroll back. Mine goes back to 2016. But it's definitely in the "view all".
