Has anyone else used a rewards credit card to pay their vendors? I'm thinking of applying for the capital one venture card to earn miles for our honeymoon. You earn miles on everything and if you spend $3000 on the first three months, you get 40,000 miles. I have no idea what that equates to but I can pay my photographer and make a venue payment and I'll be at the 3000. I'm not planning on going into debt, I'll pay it off every month from my wedding savings account. Has anyone done this and is it worth it?
