At MathTutorDVD.com, your satisfaction is our top priority. 

If for any reason you do not find the DVD(s) that you have purchased useful, you may send them back for a full refund within 30 days of purchase.  No strings, no questions. 

Ask yourself, would a large-chain superstore do this for you?  The answer is no.  How are we able to do this?  Simply put, we are interested in helping you learn Math, and we want you to be totally satisfied.  Of the thousands of DVDs that we've shipped over the years, only a handfull have ever come back...and even then it is usually because someone has dropped a class and no longer has a need for the material.

Our DVDs will immediately improve your understanding of Math or we refund your money.  That is our Guarantee to you!
