Hi Taxi,
My littlest dd was delighted to find most of the freebies still attached to the magazine( my eldest dd liked to keep things pristine!!) .. needless to say they are not attached any longer!!
I telephoned the number given on their webpage and got through to the BATMAN helpline!!!
No help to a budding ballerina !!
Let's hope Just Ballet that other ballet families like you still have their copies lurking in the loft also.
