I'm fairly certain that given Target already has a hold of Minneapolis, there's no way they'd allow Amazon to move in on their turf.
Amazon was offered $100 per employee. The total package was smaller than St. Paul offered Cray to move 200 employees. And much smaller than the $12k per employee Best Buy got for their HQ.
