What is the ratio between people who viewed a rice cooker (the group I'm assuming they target with ads) vs. those who actually bought a rice cooker?

Is it possible the ratio is so large to where while it obviously could be optimized to exclude people who have since purchased said item - the optimization is only a rounding error, and may not turn out to be worth it?

Well, I buy things from Amazon very frequently, and I have a high conversion rate between searched-for-category and bought something to satisfy the search, so Amazon ads are for things I've already taken care of >90% of the time. I'm guessing they're leaving a lot of money on the table from me because of it. But maybe I'm unusual in my shopping patterns.
