The three IPC sites involved are its women's portal, Beme.com; online TV guide UnmissableTV.com; and Uploaded.com, the online version of lad's magazine Loaded.
The agreement means that visitors to the IPC sites will be able to bid for items offered by QXL.com on specially created, co-branded auction pages.
Each site will offer a unique auction page tailored with specific content and will also run featured auctions and promotions.
QXL.com is the UK site of QXL ricardo, which was created when QXL merged with German rival ricardo.de.
