Just for comparison’s sake, I decided to do a value comparison on the three coffees in my rotation. I used the largest available size of each type since pricing is typically such that this gives you the most bang for your buck. (All dollar amounts are after-tax.)
Just for perspective, this is what gas costs (today): $1.20/L = $0.0012/mL. (Of course, coffee is a renewable resource whereas gas is not but let’s not over-complicate the discussion.)
Other note: I find the lid of the new Tim Horton’s XL to be superior to the lids of the other Tim Horton’s cup sizes. Much better at not leaking.
Measurement note: Tim’s and McD’s amounts were measured by me, Starbucks I took the size as advertised, though it’s measurement came to about 600ml. I didn’t think to dwell on how precise my measurement was since the difference seemed insignificant and the amount of coffee you get varies determined by your server. I did measure a few times.
