Looks like the newest Tracfon\Net10 phones are available online now, for sale.
LG 300g (bar phone) - $30
LG 400g (not-as-ugly-as-I-thought flip phone) - $40
Of course, both phones include $30 worth of airtime.
Also, the LG 1500 + an accessory kit is available for $50, or refurb'd with no kit for $30. The Motorola c261 is available refurbished for $30.
On the Tracfone side...
Motorola w175 (bar phone) - $15
Motorola w260 (flip phone) - $30
Also, the LG 225 (with an accessory kit) and the Motorola c261 (without) are $50, including a double minutes for life card. Decent deal, I'd say.
EDIT: The Motorola c261 is actually $40. Even better deal!
Also, shipping is currently free for all orders of $35 or greater.
