This looks like a targeted offer where chase is giving $600 in account opening bonus when Checkings and Savings accounts are opened ($300 for checking + $200 for savings + additional $100 for opening both).
I live in 27502 zip in NC and had couple credit cards with chase.
The regular offer is $350 ($200 for checking + $150 for savings) for opening both the accounts.
PS:I am not affiliated with Chase bank in anyway nor endorsing the bank except holding personal credit cards from the bank and won't get benefited from posting this deal. Disclosing in full transparency.
