I just looked at my old Curbside that Mary made me and found the 10 oz Clabber Girl Baking Powder was priced at $1.39 earlier this year. I would guess that the price is likely the same (maybe less if on sale).
If your store doubles you will pay 39¢ for a can of baking powder!
Clabber Girl Baking Powder 10 oz, $1.39
-$0.50/1 Clabber Girl® or Davis® Baking Powder 8.1 oz. or larger
As low as 39¢.
Remember you can also get Argo Corn Starch As Low As 59¢ At Publix. This is the time of year to stock up on baking supplies until the sales roll around again this time next year!
