What do you use more often?

I just put tap water in a pitcher, and put it in the fridge. The tap where I live is pretty good.

--------------------------
I'd rather be camping!

I reuse glass sobe bottles.
I usually refill at my work instead of using a new cup everyday, like everyone else.
I do sometimes refill them with our bottled water thing in our refrigerator, but I'm trying to convince them to buy some kind of water purification thing instead.
But I rarely do this anyway.

And now that you're all bored with hearing about me, I will end this here.
Sorry.
