[Not really racist!]

i guess if you wanna calculate it that way then sure, but really that isn't realistic..
5 cups week/year is 260/year, meaning you need 260 of those coffee cards, meaning in total u need to obtain 1300 (1560-260) cups... lol
and IIRC, to obtain 1300 cups you'll need to buy ~3 cases of 16oz medium cups, ~3.75 cases 20oz large cups.

i suggest you just buy the cups then, cause you're wasting coffee, other peoples' time (they'll have to brew and brew and run out cause of people who do this, thus other people have to wait longer and you'll piss everyone off)

hopefully you have no shame either, and keep in mind the free coffee promotion happens average 3 times a year for one weeks time

but at the end of the day, IMO, whoever buys one or more coffees a day should re-evaluate their priorities.. because we all know its much cheaper to just brew your own (which is do-able for most jobs) and then you wouldn't need to be thinking about these "loopholes" or calculating how much money u save doing this...

those buy 6 get one free do have no expiry and there is no set date for it to end though
i have like a stack of 50 at home.. lol
