These are the major non-Amazon retailers with online stores. You will get an idea as to what is readily available here if you browse through their catalog. Sorry for the trouble
Seeing the options, best would be to buy 212 and add RGB fan. Best alternative which is probably close to CM is https://www.mdcomputers.in/cooling-system/jonsbo-cr-201-black-rgb.html
Bit cheaper, but CM is overpriced in US too. With Corsair cheapest AIO worth anything is H80i. You could go with H60 if you don't mind noise and lack of performance compared to air coolers at the same price range.
