Walmart: Duncan Hines Cake Mixes for $0.45 with Coupon

Wow! This is an amazing deal. Walmart has Duncan Hines cake mixes on rollback for $0.78. Use the $1/3 coupon from the 10/11 SmartSource insert and get them for $0.45 each! We got two SmartSource inserts that week and they both had the coupon in it.

Thanks Frugal and Thrifty Mama!
