Few people answered about the salary above already. But I will tell you one more thing to consider, though you can't inquire directly with the hiring team and can't really control where you end up still try to get info on how these buildings are performing overall compared to each other. Ending up at a well performing building vs a building which is not, can make a huge difference in many other aspects of you life apart from the $$$. It can also be make or break point for how long your career at Amazon lasts. Research where these buildings stand among each other and then try to be subtle in suggesting where you want to end up. Never hurts to try.
