I'm all for donating so people can buy things cheaper, but I watched a story once about op shop workers who go through and take most of the decent things out to sell for themselves on ebay, so now I'm a bit cynical..

Ok, so these people did pay for the items - absolute bargain prices, but then made heaps of profit. It irks me that people who need good quality things never got the chance to buy them at a discount price. That's the main reason I like to donate, after all.

It doesn't happen everywhere of course, but how can you tell?
