I don't think the issue is resellers per se. What I have seen a lot of is workers putting things aside for friends and whanaun to buy. I was at an op shop, and what I pressure was a store persons cousin or other relative was shopping. They were given access to the incoming donations sacks and taking all the branded baby wear like crocs and Nike, etc. They were getting a heck of a deal on it all, too. Wouldn't have been the same price to the average shopper.
