I ordered Refurb Alum 2.0GHz Macbook and it took about 2~3days
I was very surprised when it came cause the receipt said that I should be expecting it on the first or second week of Feb.
Mine took 4 days as well. I think it might be faster if you customize it. If I understood it correctly, when you order a customized computer, it is shipped from the plant in China to you. If there is not customization involved, it is shipped from the US. I bought mine with added RAM. In 2006, the MacBook came with only 512 MB of memory. With hindsight, I should have bought memory modules from a third-party (way cheaper).
