I (read we) have already saved about 18-19K using flippaisa. I work in a startup and about 6 people were ordering Mac Apple there. They got a decent price offer at amazon and were just about to pay. Then I remembered about flippaisa. I already knew about it because it was IIT Jodhpur startup and I am also from same institute. We thought of giving it a try and guess what all us got about 3.5% cash back on our purchase.
Now whatever I buy I use flippaisa to save money
