If you were in the habit of ordering multiple glasses of juice while dining at a restaurant and paying 4 dollars for each glass...then you are indeed saving money........otherwise it's just imaginary savings.
When you get a takeout order and you get another free juice in a large takeout cup it's a very real savings.
so your 16 dollar sacings were all from take out??
please dont lie,
YOUR FIGURE OF 16 DOLLAR SAVINGS IS INFLATED
So you got a nice 4 dollar savings when the smoke cleared........thats amazing....good for you
