Thanks everyone for your suggestions so far.

Re: Amazon. Had a look at the Canadian site (would rather go there for easier exchange) and they don't seem to have the types he'd be looking for. Though the American ones do.

If I can't find a suitable place, I'll keep Amazon in mind for a general gift card though, and he can find the tie rack elsewhere.

EDIT: Sears sells them so if they accept my card then I'll be getting a voucher from them.
