my dad bought one online and they supply you with the chocolate. he bought it from www.sephra.com. the chocolate is divine!!!!! very very yum!!! enjoy!! xx
p.s meant to say you need a heck of a lot of choc even for the small ones or it wont flow correctly so a bar of Cadbury's wouldnt be enough. They supply you with 2kg bags and i would say we used 1kg so it flowed. you can just leave any unused choc in it or pour it into a tupperwear and store it in the fridge and you can re-melt it again
We got one for christmas and after extensive research we have found that 6 bars of the cheapest chocolate (ie. Asdas really cheap chocolate) tastes just as good as any.
