quinny buzz chair wanted!

Hi ladies! When i bought my quinny buzz from mothercare they didnt bother telling me i needed a cover for the second seat that i didnt even know existed until i started playing with it. As its the limited edition pink/orange one, they have now stopped making them. Ive been looking for one everywhere but no joy.
If for any reason anyone is selling theirs could you please let me know.

Thanks. x
