If anyone else has bought their dc's an Imaginext Batcave and has noticed you can't buy any baddies yet- I (sadly) emailed Mattel who said there should be stocks in the shop before Christmas- Argos (main stockist) Tesco Direct, Smyths, Toys R Us - but they couldn't give me a date. It'll stop me paying some obscene amount for a Joker on ebay.
Seeems silly they're promoting it all over the telly and they don't have any of the extras in the shops yet.
