This is like Amazon recommending the exact same item you just bought, sometimes from a different brand or vendor. "We see you bought a toaster, surely you need a hundred more."
Maybe they just want you to be unhappy (as the paradox of choice says, if you only had a few options for a product, you'd pick what you think is the best one and be happy with it; if you had hundreds, you can't compare all, so you'd pick one and wonder if it was the best choice).
Maybe Amazon knows that unsatisfied customers continue spending money... Hah, great dark pattern if so!
