Switch to Champion Energy Services. Get discounted electricity rates and a special $25 credit on your first bill when you sign up using referral id 1002120003. Be sure to put this in the referral id field, and not the promotion code.
I switched from TXU and am saving 40% on my electric bill. I saw other coupons codes and promo codes for Champion Energy Services, but the $25 instant credit on my first bill was a better deal.
I'm sure it will be for you too!
