Here is a tip
I use the
Buy Hatke extension for price comparisons, adding coupons automatically at checkout with just a click and checking the price history of the product.
The best part of this extension is that you can set an alert and monitor the price of a particular item (no limit to the number of products/items you can monitor). So the moment the price drops, you will get an email stating that the price of the product has dropped. This particular feature has saved me so much money over the past one year.
I remember buying an American Tourister backpack for ₹1168 whose MRP was ₹2650, thanks to the price drop mail.
Its a must have extension if you shop online regularly.
