You can go to Lajpat Nagar ( Indian,slippers,home appliances etc.). Rajouri (there you can find clothes basically and cheap slippers all at low to high rate). Kamla nagar( best for girls to buy clothes from Brands to stalls ). Karol Bagh. You can also go to Model Town, cp, district center(Janakpuri: I prefer this place its good for all the stuff and has great food ;Marconi samosa types). You can go to any of these markets as per your convince and the kind of stuff you need to buy.
