I don't know how it's done in the philippines but here in europe the customs and taxes are paid directly by framework. That's because EU laws force companies to portray the price including taxes and have to directly pay them with your order.
Maybe your country does the same? But nontheless it would be pretty easy to find out:
Go on the framework website and choose your laptop. Add it to the cart and see if it includes taxes. Then you would need to know the tax rate of the philippines on electronics and calculate them in. Now you know the price it will cost for the laptop to arrive (I assume that the shipping is free everywhere like here in europe)
