Want to purchase iMac 21.5" i3 CPU with pre-loaded iWork, large size "wired" keyboard and TrackPad. Based on Online Store selections, I can select iWork pre-bundled (for discounted $69) and large size "wired" keyboard for free. Not too sure if BB or BS store will over these free inclusions. Question: Do I buy "online", do I buy at my local FS or BB store, or should I buy at my local Apple store? If wondering, FS, BB and official Apple store are only a few blocks away from each other. If I need to return / exchange the iMac box, which "source" could treat me with less hassle? Don't think I need to return it (due to technical problems) but "just in case" situation... thanks.
