Saving money
| Aep raised my rate from 6.5 to 1 point something so I switched to a new supplier I saved money for approximately 6 months then they jump my rate I switched to constellation and got my rate back down however AEP is still crushing me on the delivery charge there should be some kind of a law stopping AEP from their price gouging since everybody is stuck using them for a distributor. With constellation my bill is only about $170 a month but then you have to add aep's $250 distribution charge on top of that and throw in some taxes and lo and behold you're up over $400 every month again. Try paying that on a measly disability check, should I eat or pay my electric bill? | |||
