Charity Cards - NOT amateur radio

My wife was about to buy 40 Christmas cards from a charity online. They looked nice and were quite good value. We don't mind paying a bit more for a good cause. Then, we got to checkout to see an additional £4.95 added for delivery. We cancelled and that charity lost out. For the delivery cost we could have bought another 15 cards from a different charity. Not only that, my wife "unsubscribed" so she no longer gets emails from them. In several ways this charity has lost out. It has lost our custom and our goodwill. In future we hope the card price is inclusive of delivery. Simples.
