With fuel prices where they're at, are you guys really that surprised at shipping costs? Just be happy you have that option available. If you were so inclined, you could always hop in a car or plane and transport those packages/envelopes yourselves.

This master cylinder kit easily fits in a USPS $20 flat rate box. These charges are over three times that. This isn't reasonable. I have the money but stuff like this pisses me off enough to NOT buy just on principle.
