Brewing tea is quite easy. Go to an Indian store and buy a 1kg pack. We get 1KG pack for your 300 INR in India for excellent tea. Thats less than 5$. With markup and all 1KG tea of good quality(eg. Taj Mahal) should be around 10-20$ in Indian stores in any big city.
That 1KG pack will brew around 500 150ml cups of tea for you.
Add milk and sugar to taste.
Here is the recipe. Remember this is how tea is made in India, which is kind of like the home of Tea. British just borrowed it and consider those silly tea bags as tea.
Lets say you want to make 300ml of tea(2 cups)
Take 300ml water.
Add sugar to taste. If you have a sweet tooth you would need around 4 teaspoons, otherwise most people do fine with 1 teaspoon each or 2 for 300ml. Use cane sugar.
Start boiling the water, and as you start seeing the steam coming, put in the tea leaves. Add 1.5 tea spoons
This figure is relative. Some like tea bitter, so you would need 2 tea spoons
Keep boiling the water with tea leaves. Once it starts boiling, i.e reaches around 100 degree C(violent water) keep boiling it for 1 minute or so.
By the end of a minute or so you would have 250ml water left. Add 50ml milk. Or add 70ml if you want it whiter.
Bring it to a boil(the mixture would start rising) and turn off the gas, and cover it for couple of minutes, sitting there.
Now pour the mixture from a sieve and throw away the spend leaves.
Drink and enjoy. Not expensive.
Some further tips. If you like a strong spicy flavor, add 1/4th teaspoon of cinnamon powder along with tea leaves.
If you like to have gingery flavor(excellent sore through remedy), put around 1 table spoon of crushed fresh ginger
If you like aromatic, add 3 small crushed cardamom cloves((a pack of 100 cloves costs around 3-4$ at Indian stores.

Cardamon pods -> http://nhastore.com/Cardamon-Pods-Whole-Green-1-Pound-Bulk--P884492.aspx?utm_source=google&utm_medium=Product_Search&utm_campaign=google_base
Remember one cup tea needs 1 clove of cardamom so even a 30$/1lb pack will last you for 500 cups or so or even more.
If you ever make a vacation to India, buy 5kg tea and store in air tight container(it will not spoil). Will cost 15$ or so. Cardamom will be 5-6$ for 1kg pack.
Once again, lemme tell you, british do not know tea. That is not tea.
When british first discovered tea, they used to bew tea, throw away the water and eat the bitter spent leaves, and then complain that Indians eat such vile stuff
Tea has to be brewed, and the first 10-15 cups will not taste very good.
Slowly you will realize how much milk, or how much sugar, or how much tea leaves you need to add.
Watch some Indian youtube videos for tea making. You will find some where 300ml water + 70ml milk and mixed and then boiled. After the boil the burner is kept on slow and tea leaves are added which are then brewed on slow flame for 5 minutes.;
These are all variations. Experiment, and you will find what you really want.
And its a cheap cheap way to prepare tea.
In India we often make 10 cups, keep in a thermos, and for the next 5 hours we can keep microwaving and having. However after 4-5 hours, the taste starts going bad.
