If you haven't ordered yet, I have always found amazon.com to be cheaper for HDMI cables. I just had to order a 50' HDMI cable for my projector and picked it up at amazon for $32 shipped which is a bit cheaper than monoprice. For all other cables, use monoprice though.
For example...
Amazon.com: HDMI (2 meter) 6 foot cable HQ 1080P 1.3b: Electronics
6 foot HDMI for 70 cents... yes $0.70 plus shipping.
All you need is to make sure it's 1.3b compliant which has the fastest throughput of HDMI on the market currently (oddly enough no device can support the speed so it gets throttled back anyway, but at least your future ready).
edit: Here are 6 foot cables for 26 cents plus shipping (and shipping is usually less than monoprice shipping also. Plus these are sold by Abacus 24-7 whom I've had good luck with in the past.
