Why does the marketplace no longer show what I own already?

It's like you guys are now trying to trick us into buying things more than once!  That's misleading and deceptive conduct under Australian Consumer Law!!

Please revert to showing "owned" when we are browsing the marketplace.  It's also very annoying having to constantly go back to my library to check - super ******* frustrating!!

1. It hasn't done that for a long time, if ever

2. The Library has a filter to make it clear

3. The Marketplace also shows that you own a book if it's in your cart to prevent a double purchase

Points 2 and 3 make your statement about "misleading and deceptive" invalid. Learn how to use the site, that's user error at that point.
