Duff said shopping habits had changed, and the show would build on rising demand to shop online.
Lane was more to the point. "I just want to see someone who is hot," she said.
Asa Tapatoutai, 18, who warmed up for his audition by dancing with Lane, said he hoped he would get to sell dance equipment.
Eight part-time presenters will be chosen from the 500 who auditioned.
The Shopping Channel premiers on October 1, channel 18 on Sky and Freeview. The show will also stream live on a website.
Lights, camera... talk!
Bright lights blind me as I stare down the camera.
I was convinced to try out by organisers, who said I needed to experience the pressure of auditioning.
So, I took a deep breath, stood on the white line in front of the camera and wondered how on earth I would talk about a pencil for one minute.
The organiser nodded and said "start". I told five onlookers everything I knew about a pencil. It was almost an out-of-body experience as I watched myself deliver an insipid and uninspired speech.
After making sure the footage would never appear on YouTube, I took my leave, more appreciative of contestants and their shameless willingness to sell near obsolete stationery.
