Shipping from the US

[Kusuriuri]

I was looking the 2k games webstore for some Bioshock 2 items that im missing, i selected a 10 dolars item and the shipping is 40 dolars with no variation ..only UPS.
What i would like to know is, is there any service that can buy and ship the products for me in a less expensive way? i know that there are sites that will ship it for me, but they require the exact expecifications of the items, and i just dont know the exact numbers.
