Need help, regarding HP merchandise

[judy_magic333]

Hi!  My name is Judy, an American who moved to Glasgow, Scotland, 7 
months ago and got married.  I *love* the HP books and hope to get 
some of the merchandise.  Particularly t-shirts (I wear adult size 
2XL) and watches (I got a cool one out of the catalog on my flight 
here, but the strap is child-size, *argh*).  I also want to look at 
HP merchandise in general, as I may see something I decide I want to 
get.  Where can I go in the UK that has this?  Are there any stores 
in Glasgow, or can you recommend any good websites that operate in 
the UK?

Judy
