It has nothing to do with poverty. Genuinely poor and homeless people will queue at a soup trailer and await their turn for food parcels. But it's not greed, either. It's that they've been fooled into thinking consumerism is an end in itself. They all own TVs already but the dual thought that (1) they can buy a new TV at a discount and (2) there is a limited number of these discounted TVs sends the consumerist into an acquisition frenzy. Even if they are lucky and get one of the bargain TVs, they'll soon find it's an old or unpopular stock-clearance model and will be lucky to get their money back even by selling it on eBay.
