Local waste tip and recycling centre

Our local "tip" (for want of a better word) was recently complete renovated and is now much more efficent, clean and easy to use. So much so that they have recently introduced a rule that you have to show ID to prove that you are living in the vicinity in order to use it, as apparently people have been travelling from far and wide to get rid of unwanted rubbish. I have no problem with that, but they also have a "recycling shop" where goods that are able to be sold are stored and anyone can buy things there, i.e. re-vamped bicycles for their children, garden equipment, furniture and toys.

It appears that now, before the recycling centre opens in the morning, there are huge queues of vans lining up outside (obviously traders) and the swoop in and buy up huge amounts of goods to sell on. One morning when my SIL was there to try to buy a bicycle for my young GS (they are on a tight budget, like many young families today), a trader managed to get in before them and bought EVERY bike that was there, about 12 in total, leaving nothing for anyone else. The same thing happened to a friend of mine who was there getting rid of some old furniture and popped in to the centre to buy a garden table - the manager of the centre said they had had several complete sets of garden furniture earlier in the day but a trader had come in and loaded up every stick of it so there was nothing left.

Do you think that this is acceptable - should there be a limit on what people can buy from recycling centres? Personally, I think professional traders should not be able to profit in this way.
