welcome back buddy. you shouldn't see an increase. i got an email from D* specifying that since i was still under the promo offer i would be receiving a monthly credit for the increase.
here's a copy of what is posted on their website.
If your current DIRECTV base package price is part of a national promotional 12-month or “Lock in Your Price for 12 Months” offer, you will continue to receive this price
for the remainder of your offer period. As of next month’s bill, your promotional price will be shown on your statement as the new price along with a credit. Note: if you
change your current base package, you may no longer be eligible for the credit.
But you had to be a NEW sub to do this promo, right ?
