Walgreens Ad lists the deal as follows:
Ice Mountain Spring Water (24 pack) - $3.49
Get a $1 Register Reward (Nestle)
= $2.49 after Register Reward
But the register is spitting out an extra $1 Register Reward from Energizer!
This makes the Ice Mountian 24 pack only $1.49!
This is probably a mistake so get this deal sooner rather than later!
