USB Power Cord

I didn't receive the type that has the coiled cable. I was sent one that has a little in-line box, and a threaded cap on the end that connects to the toilet so it won't accidentally get yanked out. I am satisfied with it. What I'm not satisfied with is the cost- it is HEAVILY overpriced. What I paid over $30 for, could be purchased on eBay or anywhere else for less than half that, shipping included. I'd go as far as saying it's a rip-off, but I guess that's the price you pay for convenience if you don't know much about electrical stuff and don't want to do guess work about which cable you need.

I think when ordering it should be an optional attachment vs what’s automatically sent. I paid 10 bucks to ship a $22 item.
