What do you mean by links? You can click on the submit products tab and you could list out the products that you wish to submit to IRC. But before doing so check the website, whether that particular product which you wish to post is already there. Because duplicate will definitely be deleted.
sorry to say that there is no seperate link for posting products. you just click on the tab submit products and do your submissions. My sincere advice is to check for that produt once before submission as the duplicates will be deleted and you won`t be rewarded any points for that. Happy posting.
