If you are looking for a spare battery
and charger for your w376g, and use more than 100 minutes per month,
you might also want to get a w370
and 450 minute card (which will double to 900 minutes) from TracFone
for $80. Since the w370 has the same battery and charger as
the w376g, you can buy one and use it for spare parts. Now is a good
time to buy this deal since the phone and airtime are bundled together for $80.
(ALTERNATIVELY, if you use fewer minutes, you could also check out the deal on the w175.)
Here's what I recommend if you want the w370 + 900 minutes deal:
Go
to TracFone.com's “buy phones” page by clicking here. If
you have a w376g, most likely this deals will be offered in your ZIP
code. If not, however, you can also enter ZIP 10101 to find the deal
I recommend. After entering the ZIP, you will look for an imagethat
looks like this:

Click on “Add to Cart,” then click “Proceed to Checkout.” From here, all you need to do is fill in your order details and complete your order.
Once your shipment arrives, you'll have a separate 450 minute card that can be used on your primary phone, as well as the free w370. If you want, you can activate the w370 and then transfer the free starter minutes to your main phone. This is what I would suggest. Alternatively, you could just keep the w370 as a backup phone for future use. Either way, use the battery and charger for your w376g phone, and you'll have 900 (or more, with bonus codes) minutes plus the spare parts for your w376g all for $80 plus tax.
