In my years as a student at IIT Kharagpur, the biggest problem we all faced in our project work, was sourcing components. For a simple transistor, we used to take a train to Calcutta–a 5 hour journey- and wade through the rain forest that was the local market. Even today, the college stores are often not well equipped.
To solve this problem, I have made many components available on amazon.in and, on this market place, my seller name is romtekzone. Here, a student/DIY enthusiast can find many components like resistance, capacitors, transistors, diodes, breadboards, sensors etc., order on line, and have the components delivered in the comfort of his home.

Only a few components in my storefront are shown below. There are many more. Visit the store front.
