The promotion savings for the hardware products are not significant. You save S$160 off the 2.0GHz and 2.4GHz versions of the new aluminum 13″ MacBooks, but only $80 off the lowest end white 13″ MacBook. In fact, considering the educational pricing, there is no price reduction at all for the white 13″ MacBook. The educational prices seem to be mostly very uninteresting.
But I guess if you are already looking for something to buy, well, you’d probably still save a few bucks. In this time of economic downturn, I’m sure any savings will make you happier with your purchase.
