I became Obsessed with finding out

Last week..my 7/11 introduced the SUPER size coffee for $3. I looked at the cup and I thought it was small. At 3 times the cost, you would expect almost 3 times the size but it certainly wasnt big enough.
Over the next few shifts I bought one of each coffee just for the cups.

I didn't have time at work to measure out the liquids but on my first evening on leave, it was all too much. David helped me do some maths. :-)

The three cup sizes $1, $2 and $3
Just eyeballing the cups you can see that as you get a bigger cup, you get less per $1 spent but HOW MUCH.
I get a tad OCD about some things. 

OK (All filled right to the brim)
the $1 cup holds 282ml  at $3.55 per L 
the $2 cup holds 387ml at $5.17 per L
the $3 cup holds 449ml at $6.68 per L

so... if you want a big coffee, but want to get the cheapest or best value from 7/11 get 3 cups of $1 coffee or go back 3 times.

I'm happy now. :-)
