Stock up on Hershey’s Cookie Layer Crunch Candy Bars at Walgreens this week! Single Hershey’s bars are on sale for $0.69. At my store, they weren’t tagged as $0.69, but they did ring up that way. (They were tagged with a monthly sale price of two for $1.50.) Use a $1.00/2 candy coupon to pay $0.19 each.
