Too many factors to answer your question. What brand, loose or bags? How many servings do you want, what flavor, etc
"A few dollars"; depends heavily on the brand, flavor, country of origin, etc. Inexpensive brands are available, as are expensive premium brands.
Wide variety of tea to choose from, all with different prices
Like Adam said your question I s vague.
In whole foods there have various brands of tea in packs I haven't any idea about your choice
