Where do you buy pre paid electricity cards?

You can purchase prepaid cards at your local department store (Walmart, CVS, Walgreens, etc). When you purchase your card in the store you will have to pay a fee upfront and may have to add money depending on the card you choose.

http://tinyurl.com/67p8qkl is also a great website to get a free prepaid card. They offer health care benefits and also provide credit building/reporting. I personally have 2 of these prepaid cards and love the service I receive.
