That specific item isn't on Amazon. The closest they have from that vendor is an extension cable.
Insignia must suck pretty bad. Only two sets of cables from them on Amazon... one is that extension (which isn't prime and costs more to ship than the object), and one is a 3 foot version of OP's cable... which is $52.
Seeing people shop at physical stores is like watching my parents use a computer. Bless their hearts for trying, but they're not doing it right.
(Edit: Just re-read that and it sounds like I'm yelling "rawr, you're wrong about the cable." Didn't mean it that way, just got curious and looked it up.)
