Bomb Shop
A Link to the Past
The Bomb Shop appears in the Dark World. It is situated exactly where Link's House appears in the Light World. The shop is kept by a strange (if polite) creature. At first he sells only regular bombs, but later in the game he will sell a special Super Bomb that will allow Link to access the Fairy Fountain at the base of the Pyramid of Power, where the Silver Arrows and Golden Sword can be acquired. The bomb can also be used to open a door into the small hut in the southwestern corner of the Village of Outcasts.
Ocarina of Time
The shop in Goron City sells bombs in many different quantities. It also sells a few other non-bomb-related items, such as the Goron Tunic.
There is a shop in the back alley of Hyrule Castle Town. This shop is only open at night. This shop sells Bombchu exclusively. Once particular bundle of Bombchu has been purchased, its spot will be replaced with a "sold out" sign. The store's supplies will not be replenished.
The Flying Carpet also sells only Bombchu. However, the supplies here never run out. The catch is the high price, a staggering 200 Rupees.
Majora's Mask
The shop is located in the Western part of Clock Town. The shop sells the usual Bomb as well as the mobile bomb, the Bombchu. Also, after saving the old lady in Northern Clock Town, the shop will sell an upgrade for Links bomb-carrying capacity. There is a second bomb shop that is located in the Goron Village and sells the Powder Keg by the Biggoron for 100 rupees. However, the shop in Clock Town sells these kegs for 50 rupees by another Goron.
The Wind Waker
The bomb shop is located on the southern part of Windfall Island and is owned by Bomb-Master Cannon, the only bomb maker in the entire sea. At first, Master Cannon's bomb are far too expensive for Link to purchase, so Link can't obtain them yet. However, after the pirates come in and steal his precious Bombs, he lowers the price to be quite reasonable. If Link is in need of some extra rupees while at the bomb shop, he can always climb up the outside of the building to the platform above the sellers head. On the platform is located a bunch a barrels and pots that hold a bunch of rupees.
Twilight Princess
There are multiple places to purchase Bombs in Hyrule in this game, but only one true bomb shop and that is located in Kakariko Village. This shop is owned by the mechanic of the village, Barnes. In the beginning, he only sells Link regular old Bombs and informs you later that they can be used to create Bomb Arrows. Later on, he will then sell Water Bombs and eventually after that, Bomblings which are similar to Bombchu. Barnes will also buy back bombs from any of the bomb bags you have for a deflated price. However, if you wish to sell your bombs you must sell all of the bombs in the selected bomb bag.
Around the store there are a bunch of warning signs that say not to use any flammable objects in the store. So if Link uses his Lantern, a sprinkler system will turn on and put out the Lantern.
