Knowing a few friends in retail you find out a lot of these things. I never buy cables from physical stores anymore. At a local JB Hi-Fi you can find the standard $70-$80 HDMI cables in the AV section, however there are similar just as good cables in the Playstation/Xbox accessories section for $20.

I also love how many Apple accessories the stores around my area have, simply because they make more selling cases and protectors than the actual device.

There is actually only one just Apple store in my town, and they have a radio commercial in which all they say is that they sell iPod accessories. It seems almost sad that it is the only thing the store is trying to sell.
