Here's Verizon's page describing their pricing. Until the promo expires (no date is mentioned at this time), the $80 data plan is increasing from 6GB to 10GB and the $100 data plan is increasing from 10GB to 15GB. This is not just for new customers - current "MORE Everything" customers can also take advantage by simply changing their data plan.
I just did it for my account. I was paying $90/mo for 8GB. With this new pricing, I switched our contract to $80 for 10GB. It isn't every day that you get to pay less and get more data. $80/mo (plus the $120/mo line-access charges) is still a lot to pay, but it's better than paying $10 more for less data. Here's to hoping that the rivalry between Verizon and AT&T continues to drive prices lower.
