As a matter of fact, Amazon is opening large centre in Poland. It's not clear to me how much of Germany's workload will it pick up, but it wouldn't surprise me if it played a major role in bargaining with the unions in Germany. Also, regarding "paying a little less and still providing a decent salary", given that the government social safety net in Poland is minimal, my guess is they'll be paying around or below bare substistence levels (2 - 2.5 eur/h) and still get workers.
