In order to get a bomb you must find a grenade in a chest (found in caverns) and have a house open. If you have the grenades in your inventory and a free house  that fit the house requirements, an NPC will eventually spawn called the Demolitionist. You can buy grenades, bombs, and dinomite from him.
