Typical trick on Amazon, charge .99 or so for a low price item, and then $12 shipping.
However they constantly say there's no difference in HDMI cables. But I ordered a cheap one from Monoprice, a 6 ft one and also a 3 ft. The 3 ft one has a very thick ribbon and is too short. However one day I couldn't get my Blu Ray player to connect to the TV with the new 6 ft cable. Sure enough switching to the 3 ft cable solved the problem.
So I'm not so sure about the whole "all HDMI cables are the same" thing.
That may be colored by distance being a big issue with HDMI cables though. Quality of signal goes down fast as the length of the cable increases. This is one of the big criticisms of HDMI cables when they were launched and one of the advantages of the new CAT-5e/6 based tech (which does not suffer this issue).
As for the 'trick', it's a matter of ordering the cable along with something else?
