How did mail order catalogs help people in more rural areas of the country?

When mail order catalogs began it was sent by railroad. Sears in the 1800's was the first mail order company. Sears was a pocket watch salesman when he came up with the idea to sell using a catalog. He began his company in Chicago because it was the railroad hub for western/eastern trains. His catalog sold everything from dolls to kit houses and every home had two things on the coffee table or kitchen table. The Bible and the Sears catalog. Since the car isn't invented until the early 1900's people in rural areas had problems getting some supplies, so the Sears catalog met those needs. All they had to do was go to the shipping office of the railroad and get their order. Eventually JC Pennies also produced a catalog to compete with Sears.
