We had a similar situation with an inhouse-ad on our site. The polished version performed ok, but just for the fun of testing, we switched to a rough screenshot image. It performed more than five times as good.

Just because one doesn't like it, doesn't mean it won't work. My learning was: Always, test everything.

I've heard this same result regarding business ebook sales at least half a dozen times. There's a sentiment in tech culture to the effect that we are free thinkers who should be dismissive of obvious sales tactics. But maybe the sales guys use them because they're statistically effective.

"Test everything" includes "test the options you're dismissive of, just in case not everyone thinks like you."

Well I am sold - but I cannot pay outside the US it seems (unless I make up a zip code)

Edit: You have my hard-earned now, after I saw the "which country are you in" - that was embarrassing, but in my defence its a terrible interface.
