As will be demonstrated, DMDD is not a depressive disorder and listing it as one is a consequential mistake. Although there are many hedges and exceptions to making the diagnosis of DMDD in DSM-5, the essential criteria are: three temper tantrums per week at a minimum and a persistent irritable mood between tantrums.
Edit: I also get the 2.50 customer-owned equipment credit too. Comcast just jacked up my cable card price from $1.50 to $9.95, I have two of them so that bumped my bill by $16.90. can tell you for a fact that this is NOT system-wide. I just paid my Comcast bill and all I pay for cable cards is the standard $1.50 per card. From what I understand, the whole additional-outlet-fee-for-cablecard-devices varies market to market.
Costs and billing are not the same every where with Comcast. More than likely you will get an Additional Outlet Fee (basically the rent of the second box). If you have access to a local office they would have the correct pricing. But it might be a safe bet to use the $9.95 fee for the second box.
