I love it! Same thing happens to me hear, my friend/co-worker thinks I am nuts! But she doesn't seem to be complaining when I bring her free stuff, she always make some sort of comment!
She needed some Zantac I give her a whole box, she says I don't want to take your whole box, I say well I don't need it I just "bought" it b/c it made me $5.00.
I don't need to get things for free, luckily I am not in a financial predicament BUT I can't see paying for something that I can get for free...Maybe this is why I am not in a financial predicament
