Today I visited the following six Crown-Heights stores looking for frozen 6-inch pie shells: Kahan's Superette, Benz's, Albany Bake Shoppe, Koshertown, Empire Kosher, and Kol Tov. Two of the stores did not carry this item. The other four all carried the same brand, namely Unger's (in packages of four). Yet, they each charged different amounts. The respective prices were, $4.19, $4.09, $3.99, and $2.99.
Can you guess which stores carried it and at which prices?
The prize for the correct guesser is a six-inch sweet-potato pie.
