CVS has the Duncan Hines Brownies priced at 12 for $10.00 this week...that breaks down to just $0.83 a box. If you use the coupon for $0.50 off Duncan Hines Brownies that I just posted about, you'll be able to get a box for just $0.33!!
This sale is featured on the last page of their ad.
The CVS I shop at does not have a large stock of food items, so I will probably take the ad into Wal-Mart and price match there.
