In reply to abr1966:
They are a friendly bunch there. Give them a call before hand and if they don't have one up I bet they'd be happy to put one up or let you put it up. But they do have a good selection up upstairs each time I've been in.
The shop doesn't necessarily have things in stock that are in stock on the website though, so again another reason why calling might save you a wasted trip (although you can always go up to Stanage for some routes!).
