You can even try shop no 595 (shop name is bonus electronics) this guy can provide you component at much lower price as compare to deepak who sold me IR sensor pair for Rs 20 which i got at Rs 5 pair at bonus electronics . As we always wnt for more and more shop at lajpat rai market we find others shops also but we are not sure about them as mostly all of them are whole seller who don’t provide product in loose , you go for more shop , only thing is that you have to be good roaming capability ,
Go for any shop which we have listed only thing is this if you can bargain things at much lower price than other than go for it , that the best you will find varity of shops with almost different prices from one other..
