just saw this deal published in todays Sydney newspaper The Daily Telegraph. Seems to be a good deal and from my previous research agl rates are quite competitive.
* NSW Special Offer: Offer not available to solar customers. You must switch from another retailer between 3 Feb and 28 Feb 2015 to be eligible. We will credit your electricity account for energy usage and supply charges for 31 days pro rata based on your first three months of electricity meter reads (including network estimates). Account fees and other charges may apply. Electricity offer not available to solar customers. Customers will receive a separate email or letter about the special 1 month's worth of electricity free offer and the 10 business day cooling off period will start when the communication is received.
I managed to get 22% but had to go through the whole rigmarole of trying to switch to origin and then suddenly AGL could offer me a better deal.
