everyday keep checking milkbasket, I had 1k in it and they gave free membership for 14 days, also everyday they are giving value pass which you can use and save on delivery. when you find a good deal (like 40 cb on 200 spend) use that to order milk and other items and in cart remove membership.They charge 15 rs/ delivery so you'll still save 40-15=25 rs.
