I used a B2G1 free Q on the Hershey's/Reese's candy, and when scanned it took off the original price of $3.49 instead of the sale price of $2.50. Sweet deal. I actually went negative with this deal and thus ended up having to purchase the M&Ms.
Total before sales, Q and ECB = $14.15
Total sales, Q and ECB = $ $13.85
Total OOP w/ tax = $0.76
