Is there someone I can contact to see if I can get a discount in buying over one hundred accounts for an institution? There seems to be no contact information for purchasing and marketing…
You would be best to contact Customer Support directly so you can provide a bit more information about why you need such things, we can in some cases pass on the information to the relevant departments.
Also you can contact us through Snail Mail here: https://www.blizzard.com/en-gb/company/about/contact.html
