Yes, this mod has been great. I really needed it since we carry books, etc. and I like to offer Media Mail as a cheap shipping option. However, other items can't be sent that way and I knew customers would ignore any instructions to not choose Media Mail if they have non-media items in their order. This way, they are shown only the shipping options applicable to their order. Installation was pretty easy and it runs well in 4.1.8. I haven't had a chance to test it in 4.1.10 or 4.1.11 yet, though.
