no problem - I was in there on Wednesday (I volunteer there) and was looking at it for 4 hours and got home and realised I'd not bought one/donated this year :( - was horrendously busy mind you with hardly a moment to think after Eid so that's my excuse!
They are being sold elsewhere, but it's the only place I know where they're being sold that's open tomorrow (schools/offices etc are shut) - there may be other places though.
