Whiterun is a poor place. I would advise going to Solitude or Windhelm
unless you are being sarcastic, its basically the central trading area in the game. Every store is all in the same area.
Adrianne (the blacksmith) right next to the gate, her husband, in the shop, so thats 2 blacksmiths, the drunken huntsman across the street, belthors general shop just down the street past breezehome, the cauldren place next to belathors.then you can go past jorvaskr and go to earland greymane for a 3rd blacksmith in the city to sell to.
Solitude, they have the clothing store, then a general goods store, , the alchemy store then 1 blacksmith and an archery store. what else is there?
Windhelm you have 1 blacksmith, the alchemy store near there, have to go all the way over to the grey quarter for general goods.
