Wanted to upgrade D3 to Digital Deluxe but it's confusing

In the Battle.net shop page for D3 RoS Digital Deluxe, it says that I will have “a total of five additional character slots primed for all-new heroes (An additional 3 more than the Reaper of Souls Standard Edition)”.

But the in-game shop (click F1 button) says that I will receive “0 Additional Hero Slots”.

So would I receive additional character slots if I buy Digital Deluxe? This is a tad bit confusing and I don’t want to waste money on misleading advertisement.

The Digital Deluxe edition includes a digital copy of Reaper of Souls, with a total of five additional character slots primed for all-new heroes (An additional 3 more than the Reaper of Souls Standard Edition).

D3 + ROS + Necromancer, you’ll have 14 hero slots.
D3 + ROS DDE + Necromancer, you’ll have 17 hero slots.

Still makes me angry that Blizzard forced us to pay for additional character slots…which I didn’t do, on principal.
