why does video professor steal my money?

Answer 1

Because John Scherer is a sneaky sneaky man! Wiki is all over this scam:

Video Professor has been criticized by many customers who claim to have been deceived by VP when ordering online. [1] In particular, customers reported ordering the product in the mail, and unknowingly being billed $79.95 for what they took from infomercials to be a free product. Apparently, customers were never explicitly made aware of the additional charge until after the credit card information was provided. Customers must send ONE of the three CD-ROMs back to the company if they do not want to be charged the $69.95 (or $79.95 as the case may be) for the extra lesson sent to them in addition to the "FREE" lesson for which they placed their order. Also they have only 10 days from the date the discs were mailed to them by Video Professor, Inc. to try out the lessons. Customers were then required to call them to obtain "permission" in the form of an RMA number to return the third CD-ROM "on or before the '10 day trial period' ends. In addition If customers decide to keep all three lessons, they will automatically continue receiving other Video Professor subjects every five weeks, billed on the same exact terms as the first shipment until they specifically call and cancel.[2][3]. In effect, customers are billed $79.95 every five weeks.
