Just got an email from Citibank (most likely targeted), to get $20 off paying Sniip bill.
The email contains unique code we can enter in the promo code section of Sniip app.
Note: They don't seems to enforce us to pay with Citi card, but minimum bill to use Sniip reward is $50
If you don't have Sniip, you can also use the random referral pool for additional $10 bonus as posted here:

They should stack, as Sniip doesn't limit how much reward you can use (whatever you have in the
rewards balance can be used).
Are you better off linking to Sniip instead of Citibank so the federal program shows up.
