In clear concise terms the issue is not " whether you get surcharged for paypal transaction or not " but if you do incur any incedental charges ,any charges such as accepting domestic outstation cheques where too you incur an extra charge, all you have to do build it into your listing price ... thats what ebay India rules are !
they are not against you charging extra for paypal , but do not mention in your listings , as overall it gives a bad buying experience for the buyer !
