GhirardelliMilk and Caramel Squares XL Bag, 15.96 Ounce/453 Grams

Does anyone know exactly how many squares are in this package. Not an estimate please.

Do these taste anything like the Skinny Cow Chocolate covered caramel?

Why is this candy shipped in an envelope? It get all crushed up!

Do we need to store them in refrigerator?
