Have you ever gone to Sainos* for a can of Coke** and seen a 2*** litre bottle of Coke** and thought
"That seems like good value for money; I'll buy that instead of my 330ml can"?
Did it once. Was tempted today but there's not much room in the communal fridge.
* or other supermarket
** or other cola drink
*** or other "large" size
