Dont want to throw cold water on all these posts that are far too wrapped up with luggage allowances, airlines, excess baggage and the Goan charity.
I to have taken out loads of stuff in my luggage but wouldnt now. Lets face it, most of what people take whilst not exactly rubbish, will be unwanted bits and pieces that you assume will be welcomed by the charity. You stuff it all into your bag, sometimes leaving your own gear behind, worry about excess baggage, rely on the goodness of airlines, burn unwanted fuel, and I cannot emphasise this enough, use a modern jet to take jumble sale tat half way across the world.
Why not just take money? It doesnt take up space and the charity can spend it where their needs lie. Sure, you dont get that warm cuddley feeling when you see some urchin running around in your kids now too small T-shirts, or the feeling that you are missing out the middle man and giving direct to a child.
BUT, money to maintain the orphanage or buy food might just be the priority and not ASDA felt tips.
