It shouldn't really get you charged up in customs, since as baccilus mentioned, those are tagged as "gifts". The only downside is that I hope you do not want to get those items immediately since shipping takes a loooooooooong time. My shipping once took almost a quarter before it got delivered. Quite curious as to what components you bought that you felt were great deals there.
And you'll surely get charged for customs duty.You may choose FedEx too but it will cost you extra.
