FWIW: might check out amazon.com, I think they still ship free, and w/o tax.
Macmall, etc. also have hardware.
Can also check: macprices.com and dealmac.com.
Lastly, don't forget that apple.com/store also has reconditioned gear. And FWIW, I would not hesitate to buy anything from there. Yes, its used, but... each and every component on the device goes through a reconditioning, vs. new things only get spot check as they are going through/off the assembly line; and besides, the warranty is a full one-year, plus availability to get the apple care too. And, prices are at times considerably better.
Oh, guess you can also always check local big-city newspapers [or Ebay too]. Sometimes you can find sweet deals on used equipment that way too...
