Got my PG from Amazon on pre-order, and thankfully it is numbered. I had scouted around for others, just in case. If anyone is without a numbered copy, Lostinvinyl (in the UK) has one on eBay - he's confirmed that its numbered and I've seen a photograph of the sticker that confirms this.
Listing is here: http://www.ebay.co.uk/itm/291382933000
All the best,
Jason
