Save yourself a packet by joining two short lengths together!
Finding genuine and authentic ways to save money is never easy, and it's rare for a retailer (that's me!) to offer advice, but here goes... If you're an agonizing few feet short on your HDMI cable run, you needn't invest in a whole new cable of the right length! For runs less than about 15m total in low-interference settings, you could try a HDMI coupler to pair two short-length cables together and achieve the same result!
How's that for saving money? And this HDMI Female to HDMI Female Adaptor (HDMI Coupler) is just the ticket for pinching pennies, because it's not only superb at connecting two male-terminating HDMI cables together into an extension, but it can also work as a simple gender-changer, plus it's backed by a five year Cable Chick replacement warranty!
Now that's some sage advice.
