How many editions of one book can a girl justify?

From Bloomsbury's newsletter:

Monday 26th June 2017 will be a momentous day for Harry Potter fans. It marks the 20th anniversary of the publication of Harry Potter and the Philosopher’s Stone, and today we announced exciting plans to celebrate 20 years of Harry Potter magic.

[...]

To mark the magical anniversary and share the excitement with fans old and new, we will publish four Hogwarts House Editions of Harry Potter and the Philosopher’s Stone: Gryffindor, Hufflepuff, Ravenclaw and Slytherin. Each edition will feature the house crest illustrated on the jacket, bespoke extra content and stunning sprayed edges in house colours.

Looks like a publish date of June 1, 2017. I can't wait to see what the covers will look like.

ETA: Booklikes records for each edition:

Ravenclaw Edition

Gryffindor Edition

Hufflepuff Edition

Sssslytherin Edition (couldn't resist)

Covers will be updated when Bloomsbury releases them.
