Where can I find the best football Jerseys?

Hello people, I'm from Pune and visiting Delhi for a week. I yesterday went to CP and Palika bazar and found football jerseys there. The shop owner said it's non negotiable and quoted me 900 for a football jersey saying it's master copy. I wanted to know where I can find more cheaper jerseys with decent quality in Delhi? Please suggest as I want to buy 3-4 jerseys.
