We got to the area too late to shop but I did take a picture of this shop where the architecture seems to mimic the bridge design. There is meter parking near the shops, but we were also too late to need to pay at the meters.
What to buy: One of the shops there was Bears on the Square which says it is one of the largest and most established Teddy Bear shops in the United Kingdom. Also available is the Ironbridge Gorge Museum Shop. Unfortunately, for the latter place, you can shop on-line, but they only ship to the U.K. If you don't live in the UK, you are out of luck.
What to pay: Print - Views of the Iron Bridge / Full Colour £3.50
Ironbridge Coloured Tankard £6.95
Ironbridge Clock £24.95
