@Rohan -- I've enabled PayU on your shop. You can now find PayU in the gateway dropdown of your checkout settings.
Many thanks for the quick turnaround time. Two questions.
1) Is Shopify entering into a similar agreement (waiving the Set up fee & AMC) with PayU - http://stories.zepo.in/post/45900289019/payu-payment-gateway-free-with-zepo
2) Does Shopify support Payupaisa (also owned by Payu India) - https://www.payupaisa.com
