I've been to the junction 32 park today, near Castleford and the Rockport/Reebok shop has a massive range of deals on clothing and footwear where you can add £1 to a second item and then get both the items for the plus £1 price.
You pay the full price for the highest priced item then add £1 and get both items.
IE i bought two rockport polo shirts for £31. The first one was £30 so i got another, added the pound and got two for £31 thats £15.50 each. Bargain.
There were masses and masses of things you can do this with.
Not sure if you can do this online though.
