I am also interested in buying some things from amazon.
I have contacted one importer and asked for some estimation.
if there is small item like for eg. $30. multiply it by around 2.8 and exchange rate
$30 x 2.8 x 91 = Rs 7,644
If the items increase the factor reduces to around 2.5.
e.g $100 x 2.5 x 91 = Rs 22,750
The above includes all taxes, duties and shipment and delivery in Lahore.
This is not final, but rough estimation, there will be some variation in it, but as the things increase the shipment cost is shared.
I am currently planning for some things I can order e.g wolfgang / klasse sealants / microfibre etc. If anyone is interested we can go for a bulk order.
btw, optimum karachi is selling meguiars supreme shine for rs 850 per piece.
