Great selection of stores and prices were much the same as Kildare Village in Ireland where I regularly visit.
There is a train to/from London which is very useful and runs frequently. Variety and number of stores is good, so you do need a couple of hours at least to go around.
If you are brazen enough, you could try get a VIP 10% discount card from the information point.
Some of the stores are quite big and have very good prices. Barbour I found was exception value for the coats.
