Jabong.com — Charging EXTRA tax as mentioned in their own FAQs

Address:

Pune, Maharashtra

In their details they have written following :- "However, VAT or Octroi may be charged on certain transactions as per government's regulation. Please note a flat tax of 5% is charged for every order where the discount applied is more than 20%. The remaining tax amount is borne by Jabong." I was trying to purchase a Puma Shoe whose deatils are as below (as shown on screen):- Original Price : Rs.4499 Discounted Price : Rs.3149 Discount Percentage : 30 % That means acc. to their rule 5 percent tax will be calculated 5 percent tax on Rs.4499 = Rs.224.95 5 percent tax on Rs.3149 = Rs.157.45 That sums up to : Rs.3149 + Rs.224.95 = Rs.3373.95 or Rs.3149 + Rs.157.45 = 3306.45 But on their site they are charging : Rs.3495.08 (which is equal to none of above) What kind of calculation are they doing ?
