**WARNING DO NOT BUY**
Pimsleur Approach is a scam!
They use deceptive tactics to lure you in then send you item after item automatically charging your credit card. You cannot reverse the charges on your card because they lie to the credit card companies telling them you agreed to buy more even when you did not and do not want more. They even charged me for items I never received and maybe never sent. They will charge your credit card hundreds of dollars more than you agreed to.
My advise is to STAY AWAY, far away from this company. If you have already given them your credit card number DO NOT OPEN THE BOX, WRITE RETURN TO SENDER, REFUSED on it and send it back. Call them and get a RMA number to write on the box if you can get one (good luck). Take parcels to the US Post Office and take a photo of you handing the clerk the packages for evidence. DO THIS IMMEDIATELY WITHIN ONE WEEK! No return postage is needed if you do it this way.
