Here's the DISH...Please note, effective February 1, 2009, DISH Network will change pricing on select programming packages and services. You will receive detailed information about these changes in your February statement. We are proud to continue to offer you great TV entertainment, the best technology, the most programming & the lowest everyday prices nationwide.
Oddly, my parents bill was just generated on 01/13/09, with service from 01/28/09 to 02/27/09 (billed a current rates). However, there's no message on their statement about the pending price increases.
It seems that the billing date on your account will affect when your prices go up.
