Our Primark isn't great, so I'm jealous of that new one!
Jo, when the Gloucester Quays outlet opened here we had the same arguments against it. It's only a five minute walk from the city centre - you walk down Southgate, go down some steps, and you are in the Docks - so people were worried about it taking footfall from the city, but it doesn't.
Most of the shoppers in the outlet come in from outside the city, it's full of top brands at great prices whereas the city centre is full of poundshops and empty units, so it adds value rather than taking anything away from the centre. Five minutes away, yet worlds away.
