Kelly I am not sure on the Spring Water deliveries but for the long term cost why don't you look into a reverse osmosis filter?
We have a bench top one and the taste is excellent. Pure, clean and crisp
ETA - or, if you have the $$ to really invest, I'd get an ecoloblue - these weren't available in Aus when we bought ours.
