call your credit cards and lenders once a year to ask them what advantages you’re eligible for. Often, they can waive fees, extend credit, and give you private promotions that others don’t have access to. Call them up and use this line: “Hi there. I checked my credit and noticed that I have a 750 credit score, which is pretty good. I’ve been a customer of yours for the last four years, so I’m wondering what special promotions and offers you have for me . . . I’m thinking of fee waivers and special offers that you use for customer retention.”
