Due to the excellent response, I have extended my half-price sale for another month.

I have put all of my audio lectures on sale for HALF-PRICE until the end of June (11:59 pm, June 30, 2015).  If you are interested, just reply to this email and I will send you a PayPal invoice.  You can pay the invoice using your PayPal account or, as a guest, with a credit card.  The audio will emailed directly to you within 24 hours of receiving your payment (usually much sooner; as soon as I receive confirmation from PayPal of your payment).

Since these are audio lectures, it is important that you have a recent edition of my book, so that you have something to follow along with as you listen.  You don't have to have the current edition, however.  Any editions from the last 2 or 3 years should be fine.  If you are not sure if your book is adequate, ask me in your email, and I will let you know.

If you would like to try out some free samples of my audio first, check out the Podcasts section of my website.
