Nothing springs to mind but a couple of questions.
What is the purpose behind saving the money?
If it's saving the odd pound here and there (I know, I know, it all adds up over a year, especially with a consumable like paper which gets used loads!) then cheapest yes, although not necessarily always the best.
If however it's about saving lots of money I'm not sure you could do that unless you get your soda machine to take greater amounts of money for the soda etc than the goods are worth (which means nobody will use it unless desperate - which defeats the purpose)
Others may have some ideas, I think there was a posting about this before - CG, I seem to recall you had something about savings?
The other way is to do a deal with a supplier. If you use a major supplier for a large percentage of supplies, see if they will do you a deal if you spend a certain amount over a year and they could give you some kind of 'kickback'
OR
for every x reams of paper, say, they give you 10 free
