Do you guys realise that Amazon just acts as a marketplace now, and the products being sold are from third parties? Now that they've captured 50%+ of US ecommerce, they've also raised many prices, to the point where they're far from the cheapest price in many cases. A random example... the cat litter I just purchased is $17.89 at Amazon, $13.49 at Walmart. Last week I bought a chair mat for $21.95 on Ebay - identical item on Amazon was $33.95 (both including free shipping but Amazon came with an additional 8.25% sales tax). Amazon is NOT raising prices, its the merchants who sell on Amazon who are raising prices. The main value that Amazon provides is fulfillment, and driving users to these product pages from third parties.
