There is a big shop in Germany, Otto, that encourages you with a €1 bonus for every review that you leave for a purchased product. Surprisingly the reviews are quite ok and you can find a lot of products with 2-3 stars on average and anywhere from 10 to 500 reviews. The problem is they also started offering products through resellers (mostly the actual brands that make the products, but I'm afraid they will also turn into a marketplace soon enough).
