Where can I get parts?

[Bulk]

I tried to order parts from ECS but they require to ship to my billing address in Australia for their first order instead of where I stay in California when I stay there once a month. The shipping price is minimum $47 to Australia regardless of what I order (including just 1 o-ring). Firstly I am not bagging them I would really like to order from them but I guess credit card fraud has made it so that it's not so simple for them........ so I am looking for other parts suppliers in the USA if anyone can help me out with their opinions. The good, the bad, the ugly

Thanks
