Funny, a few weeks ago I was going to purchase some rock waterfalls for my swimming pool and I did a bunch of surfing doing some product and pricing research. I finally ended up purchasing one from a local seller (Offline).

Low and behold, weeks later I am still seeing advertisements for rock waterfalls instead of seeing ads for new products I am researching now.

I think that explains it.
