Can you buy Elephant Parade miniature figurines from any shop in London?

I'm looking to buy one of the small versions of the painted elephants from the charity Elephant Parade in London last year. I know when it was all going on you could buy them from Selfridge's and National Geographic but I haven't been able to find them on the site recently. I have found them on the official website (http://shop.elephantparade.com/) but the postage is half the price of the elephant and they can take 8 weeks to be delivered! Ideally I'd like to be able to pop into a shop and just buy one, as this would cut out all the delivery issues. Anyone know if this is possible and if so what shops are likely to have them? Thanks!
