[checkout 0.1.18] How do I hide Shopping Cart info from Parent album, but not sub-albums?

I saw a similar post months ago but cannot track it down for the life of me!

My site in development is at http://www.milliepilkington.com/Testing/index.htm

I use checkout/checkout email and have uninstalled the default 'Cart' plugin. Children/Adults/Wedding/Other are portfolio areas for anyone to view. The Client album is slightly different in that it contains sub-albums that will be uploaded via Gallery Remote. These sub-albums need to inherit the theme and permissions of the parent Clients folder - they are then password protected (use album title for password currently).

This all works really well, but it means the Shopping cart info (Admin>Clients>Edit Album>Theme>Blocks to show in the sidebar>Shopping Cart Info) has to be shown in the sidebar of the Clients Album page in order for it to be inherited by the new sub-albums. I'd prefer 'Shopping Cart Info' to be hidden in the Clients Album sidebar so that, layout-wise, it was identical to Children/Adults/Wedding/Other album pages.

Is there a way to 'comment out' this info in the specific album page only?

Any help much appreciated
