Rare $1/2 Milky Way Single Bars Coupon (Facebook)

Update:  The regular Milky Way bars cost just $0.74 at Walmart every day, so use your coupon to score two for only $0.24 each!
 
Yay!  There is a rare coupon valid for $1 off any 2 Milky Way brand single bars, 1.76 to 2.05 oz! Note that you must “like” them on Facebook to print this coupon. I am guessing this won’t last long, so print while you can!
Even sweeter, starting next week at CVS (7/15-7/21), Mars chocolate singles 1.08-2.15 oz will be on sale buy 1 get 1 for 25¢, so I would say this $1/2 coupon will make for seriously inexpensive Milky Way bars!
