LOL...

There is difference in speed when you pay more.

For example, I bought a headamp from Canada. Posting cost USD13 alone, and I got it in a week.
Before that, I bought an Alpha CPU Cooler from USA. Postage is a mere USD8. LOL... waited 7weeks.

And lately I ask for some opamp sample from National Semiconductor. Paid USD30 for shipping and only takes 2 days. No difference? Think again...
