JC Sportline on Amazon had the spoiler for $199 for the longest time. It was reduced VERY briefly to $159 before it shot back up to $199, and now $289. It seems to fluctuate with the Chinese economy. Since they are tanking at the moment, along with our markets, I would give it a little time to see if it comes back down to the $199. Its like hitting a moving target. Suggestion: If you are interested in it, add it to your cart and check your cart a couple of times a day. Amazon will make the price adjustment for you automatically should the price change again.
Clarification to my previous post: The extra tape that I added to the corners, which is thicker than the tape they originally used, was placed in the void between their two rows of tape. None of the tape I applied overlapped theirs thus giving me a really snug fit the entire length of the spoiler with no gaps.
