What's so important about having the actual toy book in hard copy form when you can #1, look at it online and #2, print the coupons online too?
Personally, I think this is great way for Target to save an money and save trees while they are at it.
Not everyone has internet access or they might have dial up where the ad would take FOREVER to load. I know my grandma doesn't have a computer at all but she has 5 great grandkids to buy for so she would need a physical ad.
The advent of the internet is great but that doesn't stop people from needing the physical ad as well. There will always be people who don't have a computer or access and will need the printed versions from the stores.
I also like having the printed ad so I can schlepp it around and keep it as a reminder of the things I need to go buy. My kids also circle what they want and it helps me. Trees will die whether I print it at home or Target does - frankly I give Target enough of my $$ I would rather they print it and give it to me
