Do you have a debit or credit card issued by Citi?

More specifically, do you have a personal credit or debit card (not business), excluding the Costco and Chairman credit cards? If the answer is yes then you're eligible for Amazon and Citi's latest promotion: a four month free trial of Amazon's premium music streaming service, Amazon Music Unlimited.

New users can get a free month trial any time. Citi and Amazon's new deal is for a three month trial, but you can stack the two promotions for a total of four months.
