As a rule of thumb, any fundraising by the Salvo's used to result in over 97 cents in the dollar hitting the streets.
I see no reason why it would have changed- so if the Salvo's are doing thier bit in the Phillipines you can be pretty sure your donation is doing its job.
my choice for donations-
Salvo's get my cash, [and I have collected for them many times as well]
Red Cross get my blood and whatever cash I can spare,
I tried giving the cat haven's collector, next doors cat last time they ignored our go away sign, and got them confused

I refuse to donate to anyone else collecting as they are all too often "commission collectors"
