I found the coupons on the cold beverage coolers at our local Bel Air Wawa earlier today. They are .50 cents off one and are valid through the end of December.
When you take these coupons and redeem them at the grocery stores they should double to $1. At Giant the Propel are 10 for $10 and at Shop Rite they are 5 for $4. I imagine they'd be similarly priced else where too. So... FREE Propel!
