Save time and money when brewing iced tea

Might not be the season for this post, but whatever. I brew my iced tea myself and store it in gallon container. I found I can cut down on time, energy and ice cubes (that water it down), by only boiling enough water to cover the tea bags in my pitcher. After letting it steep for 4 minutes, I fill the rest of the pitcher with cold water. I can't discern any difference in flavor from when I used to boil all the water. Plus, I find it lasts (unrefrigerated) just as long as tea that used 100% boiled water. (Conversely, if I make sun tea in the summer, I find it starts getting funky the next day unless it is refrigerated.) I like to refrigerate the tea, but sometimes I just don't have the room for a gallon container. If I want hot tea, I just microwave a cup of the tea from my pitcher...no waiting for it to steep.
Bonus tip: I read someplace that drinking a lot of tea can give you some type of stones (kidney, gall...I can't remember), but putting lemon in the tea solves that problem.

The free TimBit brings me in

The husky is mine, the other is my "dog niece." The dog usually only gets to go for a drive when I'm taking him to the dog park or groomer. However, when I find I must take him for errand-running, I'm a sucker for stopping at Tim Horton's drive thru. They always have a free Timbit for the dog. He otherwise doesn't get sugary snacks, but I feel the need to reward him when the trip involves some waiting alone in the car for him. Plus, the dog likes the attention of the cashier. Otherwise, I'm not much of Tim's fan. I don't drink coffee and they are inconsistent about which locations have lemon for their tea. How can you sell tea without lemon? Inexcusable.
