Lisa Wilkinson's new memoir is being sold $10 below its recommended retail price (RRP) in a popular book store, two weeks before it's release on November 3. The explosive book - titled It Wasn't Meant to Be Like This - will detail a number of stories about Wilkinson's life and media career, including a chapter dedicated to her sacking from Channel Nine and fallout with Karl Stefanovic over a pay dispute. In Dymocks, the RRP of the book is listed at $45 - but an advert marked 'Price Drop' says the book is now being sold for $35. 'Price Drop': Lisa Wilkinson's new memoir is being sold $10 below its recommended retail price (RRP) in a popular book store, two weeks before it's release on November 3 The RRP is a price guide for sellers, but Dymocks is selling it for $10 less. What's more, a limited copy of the book signed by Lisa herself is available to pre-order in Big W for the very reasonable price of just $24. While this hasn't been labelled as 'reduced' by the store, it's still a whopping 46 per cent off the RRP. Daily Mail Australia understands the price drop is in no way related to the fact that claims in the book have recently been challenged, and is just a marketing strategy by stores to boost sales. A representative for HarperCollins told Daily Mail Australia on Friday: 'There is no "price drop" for Lisa’s book by Dymocks. Down down: In Dymocks, the recommended retail price (RRP) of the book is listed at $45 - but an advert marked 'Price Drop' confirms it's now been slashed over 20 per cent to $35 'The Dymocks price for Lisa’s book is $35 and this has always been the case. Different booksellers sell all books they stock for different prices and this is totally dependent on their individual business model.' The representative also references Sonny Bill Williams' memoir, which is selling at $34.99 rather than the $49.99 RRP. 'This is nothing out of the ordinary and applies across the board with Dymocks, regardless of the book,' they added. Daily Mail Australia have contacted a representative for Dymocks for further comment. A number of Lisa's claims in the upcoming book have been questioned in recent days, including a chapter dedicated to her exit from Channel Nine and falling out with her former co-host Karl Stefanovic over a pay dispute. Bargain! What's more, a limited copy of the book signed by Lisa herself is available to pre-order in Big W for the very reasonable price of just $24. While this hasn't been labelled as 'price drop' by the store, it's still a whopping 46 per cent off the RRP Wilkinson alleges Stefanovic proposed in August 2015 they join forces to renegotiate their Nine contracts - not unlike how the cast of American sitcom Friends famously worked together to broker better deals with NBC. But she claims he ended up ditching this idea and instead played rival networks Nine and Seven off against each other in order to secure a better deal for himself. 'Weeks later... the media became awash with stories that Stefanovic was restless at Today and looking for greener pastures – and more civilised working hours – at Channel Seven,' she wrote. Stefanovic was soon at the centre of a bidding war between Nine and Seven that resulted in him re-signing a five-year deal with Nine worth at least $2million per year. Casting doubt: A number of Lisa's claims in the upcoming book have been questioned in recent days, including a chapter dedicated to her sacking from Channel Nine and falling out with her former Today show host Karl Stefanovic (left) over a pay dispute Wilkinson's deal was worth significantly less, about $780,000 a year, and was only for two years. 'There was no doubt about it: Karl certainly knew the art of the deal,' she wrote, adding that the resulting pay disparity between them 'was so off the charts that no-one would have believed it'. However, Lisa's book also allegedly doesn't tell the full story, with News.com.au reporting this week Wilkinson had in fact earned more than Stefanovic for years when they first joined forces on Today, and it was only at the end of their partnership that the roles reversed. On Tuesday, an article written by respected political journalist Samantha Maiden reported that when Karl first signed up to the breakfast show in 2006, he was on half of Lisa's pay packet, which was a reported $700,000. 'When they were first on the show, she was paid a lot more than he was,' an alleged Nine insider told the publication. 'Then, he was able to wedge a fee increase because Seven made him a big offer. If Nine wanted to keep him, they had to pay him, which is what happened. Challenged: Wilkinson's book also allegedly doesn't tell the full story of their pay discrepancy. News.com.au journalist Samantha Maiden (pictured) reported this week Wilkinson had in fact earned more than Stefanovic for years when they first joined forces on Today, and it was only at the end of their partnership that the roles reversed 'If you look at what he's paid now, it's probably not too dissimilar to what she was offered. So, you know, you can take things in a point of time, but I don't think there would have been much difference between the two now.' This damning article - which challenges Wilkinson's most significant claim about her exit from the Today show - reportedly sent the book's publisher into a major spin. Harper Collins Australia have demanded a preview copy of the memoir be returned by the news website following publication of the story, sources told Daily Mail Australia. 'They blew up and asked for their copy back,' said an insider at the website. News.com.au editor Lisa Muxworthy declined to comment when contacted by Daily Mail Australia. A spokesperson for Harper Collins declined to confirm the allegation. Wilkinson also lifted the lid on her final days working at the Today show in an excerpt from her new book, published in The Sunday Telegraph. Claims: The news.com.au article challenged Wilkinson's most significant claim about her exit from the Today show. (Wilkinson is pictured on Channel 10's The Project) She claimed Stefanovic had given her the cold shoulder in the weeks prior to her sacking, which was prompted when she asked for a significant pay rise. She alleged she and husband Pete FitzSimons had invited Stefanovic and his partner, Jasmine Yarbrough, to attend their 25th anniversary vow renewal ceremony in October 2017. Two days before the event, however, Stefanovic supposedly contacted FitzSimons to say they wouldn't be attending because they'd extended their overseas holiday. 'In the ten days since [the ceremony] Karl hadn't contacted me, his co-host of almost eleven years, at all. No phone message, no text, no apology, not even a simple congrats. Just complete silence,' Wilkinson alleged. After returning to work, she claimed Stefanovic did not ask her about her holidays, nor did he apologise for being a 'no-show at the wedding'. Twist: Harper Collins Australia demanded a preview copy of the memoir be returned by the news website following publication of the story, well-placed sources told Daily Mail Australia 'For the next two hours, I exchanged not a single word with Karl outside of what was scripted – because for the first time, I just didn't trust myself to "play nice",' she said. However, her recollection of her last show has been also disputed, with resurfaced footage showing Stefanovic had in fact said to her: 'It's a big welcome back to Lisa. Nice to see you again. How was your honeymoon?' Wilkinson went on to claim in her book she was 'quietly fuming' because 'nearly every interview that day was being done by Karl alone'. 'For two hours, I sat there feeling completely useless. The Today Show was now The Karl Show. What was the point of me even being there?' she said. Upon learning she had been sacked later that day, Wilkinson wondered: 'Was this why [Karl] didn't attend the wedding and hadn’t spoken to me since? Was this why he never said a word about the show’s strange rundown that morning?' Not happy: Wilkinson alleged she and husband Pete FitzSimons had invited Stefanovic and his partner, Jasmine Yarbrough, to attend their 25th anniversary vow renewal ceremony in October 2017.
