Where to buy Harry Potter scarf

I am looking to buy a Harry Potter scarf for my nephew for Xmas. I have seen them on a few people so I know they are available.

I can get one on line but it probably wouldn't be delivered on time for Xmas. I have tried Smyths Toys without success.

Therefore, if anyone can tell me of a shop that may sell one in Cork City or its environs I would be grateful.

I got one in either M&S or Next, but it was about 3-4 years ago at the hype of the mania!!
