Neolithic Revolution: Why Was it Important? The Neolithic Revolution was important because at this time people started farming, new technologies were being invented and people started coming together. The Neolithic Revolution began when people started to practice farming. Some believe farming started in the Middle East, and others believed farming developed independently in different regions. Food-gathering women discovered that if seeds were planted on the ground, new plants would grow in a year.
Price of a Stamp. The current price of a first class stamp is 49 cents. A domestic first class letter (1 oz.) is 49 cents. The price of each additional ounce is 21 cents. It will cost you 34 cents to send a domestic postcard.
Standard mail, such as first-class letters and postcards, make up 76% of the Postal Service's sales -- all of which have prices capped by Congress. Postcard stamp prices will drop by a penny to 34 cents, and international stamps will cost $1.15, down from $1.20. There's hardly anyone alive who remembers the last time the price of a stamp fell. That was in July 1919, when first-class stamp prices dropped from 3 cents to 2 cents.
