Verizon is currently offering a "Customer Appreciation Service Credit" to its landline customers. The credit is for $40 and can be applied over 4 months for customers in California, as well as other states (see list below). All you need to do is call Verizon at 888-226-0799 and tell them you are aware of the promotion. There is a mailing for the promotion, but you do not have to receive it to take advantage of the offer. If you run into any roadblocks, call again, and repeatedly tell the customer service rep the name and details of the promotion. You might also try calling 800-483-3000 (don't press or say anything, just wait until you get a representative).

The promotion should be good for the following states (let us know if you hear of any more):

CA
FL
ME
MD
MA
NY
NJ
OH
PA
TX
VA
WV
