In a follow-up post, Stuart told her 11,600 followers the sale was an experiment.
"We're not taking this seriously. We just want to see what happens," she said.
"We might not even get bids but it's all part of the experiment."
Doritos Australia decided to reward the Queenslander for her "bold entrepreneurship" and "ingenuity " after the discovery of the puffy shaped chip.
"It's been a whirlwind couple of days for Rylee and her family and we've loved following her story," the company's chief marketing officer Vandita Pandey said.
"We've been so impressed with Rylee's boldness and entrepreneurial spirit, so we wanted to make sure the Stuart family were rewarded for their creativity and love for Doritos."
Since Stuart's unique eBay listing, other people have followed suit, hoping to profit from "one of a kind" puffed chips.
