Sales price not coming up when added to cart

I was just going through my email, I got this E-mail: ClubNorton Newsletter: App Attack!: Four things to think about before you download. I went on to read the menioned article ( http://us.norton.com/addicted-to-apps/promo?om_em_cid=hho_email_clubnorton_jan12_nam_us_A ), in it was a link to the page for Norton Internet Security ( http://us.norton.com/mobile-security/promo )

 

I looked over the product, liked what I saw and liked the 14.99 price tag even more, enough for me to go ahead and buy.. almost.  I got as far as adding the item to my cart but immediately noticed the price given was 29.99, not the 14.99 deal that I thought I'd be getting.

 

So my question is what's the deal here, the page says one price, the cart says another.  I would be a little more understanding if I hadn't checked my inbox in a week or more and it had gone 'off sale' but the newsletter containing was just sent to me a few hours ago. Anyone know anything about this?
