Every product that we list on this site is sold via the payment processor Clickbank. Clickbank lists statistics on these products in its marketplace. One of these statistic is the EPS figure (Earned Per Sale). This is the amount that an affiliate that refers a sale can expect to be recompensated for the referral. By comparing this EPS figure to the product price and commission offered, we can create an accurate estimate of the amount of refunds being requested for the product.

Please note, however, that Clickbank does not reset the EPS when changes are made to the product price or when products are addded or removed from the account. For this reason, the refund rate can be inaccurate and we therefore allow publishers to send us screenshots of their Clickbank account to prove their true refund rate. Click here if you are a publisher and would like to do so for this product.

We do not sell Managers Need To Know or any of the products we list directly. In this sense we are not like, say, Amazon.com. Instead, we aggregate information about other peoples' products and allow you to make the most informed purchasing decision. So we are more like a price comparison website than an online store. Like all price comparison websites, we receive a commission from the product publisher if you purchase from them.
