I don't think it's reasonable to call bargain hunters "low lifes".

Here in Canada, out big discount day is Boxing Day, and in recent years, it's become "Boxing Week".

Just like in the USA, stores will publish flyers of everything that's going to be on sale on Boxing day, and just like in the USA, people will start lining up at 5:00 o'clock in the morning or earlier to be first in line when the store opens to make sure they get what they're wanting to buy.

Money isn't of equal value to everyone. The more money you have, the less valuable and important it is to you. The people lining up to get those Black Friday or Boxing Day sale items are from the lower economic strata of society, that that doesn't make them "low lifes".
