Flush Puppies

Has anyone tried these?
They are pricey... Wonder if I could find them online cheaper. Sorry for the blurry picture, it was taken with my iPhone on the plane!
Do you know that doggie poo run-off is bad for streams and rivers? I know, you'd think it would be a natural occurence you wouldn't have to worry about! I read an article about this issue recently that explained it really well, if I find it again I will update this post to include the link.
Thankfully, our pup dog Koda only does her business in our yard (we didn't purposely train her this way but we like it). We let her poo deteriate in the grass. It really hasn't been an issue for us since compared to other doggies we know she doesn't poop as much (we're convinced it's because we feed her Purina ProPlan). Obviously when we travel we have to clean up after her... But from what I've learned recently we should be picking up her poo all the time. Ugh.
I am selfishy posting these pictures of Koda because she's just a cutie and I miss her! One of her favorite things in the world is fresh cut grass :). I had to drop her off at the kennel today and it was harder than usual because I could hear her whining in the back... probably because she could hear me talking to the girl at the desk about her fear of thunderstorms.
Would you a) use Flush Puppies and actually flush them down your toilet, and b) pay $2 for 15? How do you manage your dogs/pets poo? Really, I wanna know!
