The house I own at the moment was owned by a very old lady who I think must have been taken advantage of by charities - every single day there is post for her from one charity or another, I saved it all for a month recently (to post it all back) and it was over a carrier bag worth full... some of them even send money asking for you to send it back plus more, not to mention pens/other cheap
crap items.
I am all up for donating to charity - but it's sad to see that a vast sum of money is just wasted
