Where Do I buy the Game??

Hey, So I want to get into dungeons and dragons. it looks really fun, and I'm terribly bored, I've tried looking on amazon, flipcart etc. but the starter set for the dungeons and dragons board game is really expensive like 6000-10,000 rupees. where do I buy a good starter set? Under like 3000 rupees? is it even possible? LMK please.
