Customs duties in PK on ordering stuff online?

Hi! has anyone here had any experience with ordering hardware/software from international online shops like Ebay/Amazon?

I want to order some PC collectors editions and PlayStation3 games and some small consoles like Vita or 3DS and phones, will there be any Customs/import hassle involved or will they reach me directly via courier? and what are the official tariff on electronics? is it possible to avoid the fees somehow because I am buying these for personal use and not reselling etc?

Any advice will be really appreciated! Thanks! :)
