Here are audio files of me, Grant, teaching Lessons 1 and 2 in my Intro Calculus book.

You can buy the complete set of my audio lectures teaching my entire book for $50 + GST.  That's less than $1 per hour!

If you are interested, reply to this email, and I will send you a PayPal invoice.  You can pay with your PayPal account or with a credit card if you do not use PayPal.  Once the invoice is paid, the audio will be delivered straight to your inbox within 24 hours.

Anyone who buys the September 2014 edition of my Intro Calculus book ($90 + tax; available at UMSU Digital Copy Centre, room 118 University Centre), can order my audio for HALF-PRICE! 

That means the cost is only $25 + GST.

To qualify, when you email your request for the audio, simply mention your Order Number given on the top right corner of the Prepaid Package receipt you were given by the Copy Centre as your proof of purchase.
