Yeah I was going to say the same thing. TAKE THE HDMI's BACK!
I learned (thank you Sprry75) when I bought my TV a couple years ago that they rape you on HDMI cables at BB, and you can get them shipped to you for free usually,f or like $10. I have extras even. Hell, Comcast even gave us HDMI cables with our DVR.
Take those back, and laugh even more on your way to the bank.
