Amazon is probably more well placed to make an informed decision, as it’s most likely the products you look at, but don’t buy, that you are probably interested in. Unfortunately in reality that doesn’t seem to be the case. Last week I bought some wireless headphones, and now my feed shows a bunch of those. It also keeps showing me books by an author who I bought a series from, but never finished (on Kindle). And a selection of Spanish books, that my wife needed once for her studies. And for some reason a load of large kitchen applicances.
