I don't care that much for any of them, my wife makes cookies that are many times better than the GS cookies. 

If/when the Girl Scout comes to the door to sell cookies, I just give a donation to their troop and tell them to keep the cookies.

I can't recall the exact numbers, but the troop gets a pretty small percentage of the cookie sales. Someone somewhere along the line is making a lot of money, but it's not the Girl Scouts. Or at least not the local troop.

Boy Scouts around 'here' have a sale where they sell popcorn, we usually just make a cash donation to them as well.
