What is cost of adding InDesign to my Photography package

There is no email customer service. Warning, scammers may contact you privately pretending to be Adobe staff. Adobe will never send you a private message asking you to email an account that isn't @adobe.com, or use Skype. Adobe never ask you for their password. These scammers want your Adobe info, credit cards, your money and control of your computer, please take care.

Right now the cost, less any incentive plans you may have available is $20.99US/mo., paid at an annual price of $239.88. If you need it short-term, or prefer to pay month-to-month, it'll run $31.49/mo. 

There are educational discounts, and may be some other special plans that I don't know about. But your best bet is to get with Adobe Customer Service. Like a lot of businesses dealing with the COVID-19 shutdowns around the world, Adobe is scrambling to do what it can as conditions are changing worldwide and business/office work models are constantly adapting to accommodate them. Please be patient with them; I can honestly say the company isn't intending to give you short shrift. They'd like your business.

Hope this helps,

Randy
