Just reserved one, it's in the argos half price toy sale, which is pages long, and thought it deserved it's own post as it's not an old toy, and highly sort after (with the kids i know at least). Currently out of stock for home delivery, but loads available to reserve from my local store!
Plus the argos one has a special offer :- Buy the My Little Pony Amusement Park and get 2 Bumper Cars and 2 Rollercoaster Cars with Ponies free. Offer is included in pack, please note it will not show in your trolley. Offer ends 16th January 2009.
