Tomorrow I am buying my first Mac. I know it will most likely be the 27 inch iMac. I was planning on buying it at the Apple store but Bestbuy just came out with a deal when you buy an iMac you get a 500 GB Iomega Go hard drive for free. I am also a Platinum member at Best buy and could rack up a few extra points buying it there. Is there any advantage to purchasing my iMac at the Apple store or Bestbuy? Thanks in advance for the help.
