I'm no fan of either - Allegro has Amazon executives and nearly identical Prime-free shipping strategy. Pretty sure Allegro has the same effect of monopolizing and driving up prices as Amazon has.
I find the eBay-esque artifact interface absurd. It's likely Amazon hasn't found a way because an environment that isn't a monopoly isn't attractive to begin with for that business model.
