Warning! ... All the discount retail stores know that when you pick up your new TV, DVR or Blu-Ray Player that you will need an HDMI or other cables to hook it all up...
With a little foresight... You can save a ton of money by ordering online in advance....
Monoprice.com is one great source...
I recently read on some site or other that checking Amazon too might reveal bargain prices...
My geek friend Moe turned me onto Monoprice a few years back and I always check them first...
He also tipped me off to NewEgg.com where I have many bargains on routers and other peripherals over the years...
Look before you leap...
