I'd rather have a larger paycheck.
I would take the 25c/day pay cut it would cost to have someone stock the fridge with sodas so that I didn't have to go to the bother. On one hand "perks" are about employers differentiating without paying more, on the other hand there are economies of scale that do your employees a lot of good, if you pick the things that a good portion of your employees partake in. Free coffee/tea is pretty standard for this reason, why shouldn't that apply to other (more modern) common consumables?
Of course, don't let your company health care provider hear that you have a fridge of 240-calorie insulin-bombs stalking the corridor...
