Not as slick as deals in the past, but not terrible either. Vitamin Shoppe continues to make it hard to combine coupons with these offers.
6 x Cases + 10% auto-ship discount = $105.27 / 72 = $1.46/can
If you sign up a new email you get a one time 10% off discount code, bringing costs down to ~$1.30 / can.
Vitamin Shoppe is usually very good with taken care of damaged / leaking cans during shipping. They usually send a new full case at no charge.
