SN30
First deal, apologies for errors. I am not affiliated with ITProTV or Security Now.
ITProTV have an offer at the moment for a monthly subscription that is normally $57USD a month. Its down to $29USD a month if you subscribe during January but the Security Now podcast offers a further 30% off with the coupon code 'SN30' making the total monthly $20.30USD. I think this is the cheapest it has ever been.
For those not familiar the company offer courses and video based tutorials to teach IT subjects like Cisco, Microsoft, Linux etc. and I believe some of those courses even can prepare for Microsoft, Cisco certification etc. in the industry.
