What am I missing here?

Just came across this on the Games-Workshop website regarding the service available at Warhammer world, Nottingham. I don't know what it means, could mean nothing, might have been something to do with the school league, but as I had to cancel plans for going down this weekend I felt that I needed to ask, do any of you guys know?

 This is what was said on the website:

"Due to work behind the scenes, we can’t offer our same day order service on Saturday March 22nd, but you can… Place an order with us before the 19th and collect it here on the 22nd. Or.Or place an order with us on the 22nd and have it delivered to your home."
