I ordered it and a number of other accessories directly from Samsung. It was $19.95 vs. the $24.95 from the third party link.
Also ordered the 3.5 mm adapter - as I want to try a better headset/microphone than the samsung one, which like the built in mic on the Memoir - is TERRIBLE when trying to record a live video of a music performance.
Also getting the car adapter. With a turn-by-turn app like Amaze, it eats up the battery pretty quick while driving.
Almost bought their bluetooth earphone headset, which was on sale through March 31 at a price below other sites ($99), but passed on it. Maybe should have gotten it now - as it will work with just about anything.
and how did the 3.5 mm adapter work out...and what about the tv out cable. im thinking about getting them
