Virgin Mobile has put their flagship Samsung Galaxy S III 4G LTE phone on sale for $319.98 for one day only. That's $80 off the phone's regular price of $399.99. Shipping is free. The sale ends at 7 AM Eastern Time tomorrow 7/23, while supplies last.
In addition, new Virgin Mobile customers who purchase the S III during the sale and activate the phone on a new Beyond Talk account will receive a $70 account credit within 30 days after activation. That's equivalent to getting two free months on Virgin's most affordable $35/month Beyond Talk plan, which comes with unlimited messaging and data (throttled after 2.5 GB) and 300 voice minutes.
Update: The sale is over and Galaxy S III price is back to the normal $399.99. However the $70 account credit is still available for customers who purchase and activate the Galaxy S III or the $179.99 Samsung Galaxy Ring by 7/31.
