The 36-year-old tweeted links to all of the items, which included a signed tour brochure and the trousers she wore during the big announcement in 2014.
According to reports, Jo received mixed prices for her sales – with a signed picture of herself going for just 99p.
But, while some have hit out at the former Celebrity Big Brother star for essentially selling off her memories, it appears Jo is just freeing up space as she prepares to move house.
She tweeted: “Looking forward to a nice early night tonight !!! Ready for a full day tomorrow packing and getting ready to move !!! #excited [sic].”
Geordie Shore star Charlotte Crosby has also jumped to Jo’s defence, insisting there’s nothing wrong with using eBay to make money.
Writing in her column for Star magazine, Charlotte said: “Jo O’Meara was criticised for flogging S Club memorabilia on eBay, but I don’t see a problem with that.
“I’ve had an eBay account for years and I sell all sorts, from clothes to signed mugs.”
Do you think Jo should be criticised for selling off old S Club memorabilia? Let us know on Facebook and Twitter.
