It seems like many of the credit card companies are trying to entice customers to spend on their card.
I got an email from Priority Club Visa stating that if I spend 1,500 from 4/1 to 6/30 then I will get another 1,500 bonus points. There was no registration, just a notification to spend. Make sure to sign up for email notifications to get these promotions.
One of my Bank of America cards also had a similar promotion where I would get 5x points up to a bonus of 2,500 points.
Have you received any other promotions? Will this influence your spending habits?
