From the authors’ website:

“You can't buy a hard copy of the 8th edition, but instead can rent (and then choose/pay to keep the hardcopy if you want a hard copy book). You can rent a copy or subscribe to Pearson+ from our publisher, or rent a hard copy or purchase a Kindle version from Amazon, or rent a hard copy from VitalSource.”

That’s just… odd!

It's probably intended to elide transfer of rights of first sale by tracking it as a rental with no intent to term in which to return.

It's bullshit.
