This is how the US does deals...

I'm currently in Macy's flagship store at 34th Street, Manhattan. Everything in the store is reduced by at least 25%. Some big name brands, like Levis for example, are as much as 50% off. But get this - there is an additional 30% off the reduced price as well. Macy's is one of the biggest, most recognised retailers in the world. They don't have to sell their inventory for such reduced prices. But they obviously recognise that people both need an incentive to spend their hard earned money at their store, and that money is still pretty scarce. How many UK retailers would put on a sale of such preportions just weeks before Christmas?
