Feed those in Need

Okay, so here's the thing.  If I purchase something from a company whose label tells me they will feed this or donate to this cause, I would expect that they would do just that.  But lately I have been inundated with products whos packaging leads me to believe just that, yet in the fine print I must log onto this website and enter a code. 
The thought that I must further take my time isn't necessarily irritating so much as it is inconvenient and a rediculous attempt at the company to further embelish their products into my mind with their advertising. 
It only takes a moment for me to enter the code, but I don't always have the time and many times I am not thinking about it as I am getting ready to throw something into the bin. 
Whatever the cause, be it cleaning up oil spill animals, feeding the American Children, feeding the rest of the world, donating to breast cancer, lung cancer, or any other numerous causes, just donate the damned money.  The company knows how many were purchased and have set aside the money, just donate it out. 
I cannot fathom why a company would make the consumer enter codes for donations other than as I stated earlier that they can further advertise their products, unless it is so they can CLAIM to have intended to donate said amount of money, even they they predicted that not even half of it would be used.  This would allow them to temporarily look good in the public eye, "We have set aside three million dollars for donation to blank charity!" but never advertise that it was not even three hundred thousand they actually gave.
Now, Yoplait! with their marketing scheme actually requested to get their aluminum lids back, and while just as arduous, serves a small purpose (recycling makes money).
It comes down to this, you, as a company, want to give money to charity, either just give it, period, or simply tie it to sales, don't expect the consumer, many of whom already give to charities of their own any ways, to do further leg work.
Just an Old Soldier Ranting.
