Breakthrough french 1 book with 4 cd's for sale

What a great way to learn French!!! The book and CD's are very new, never opened, never used, still in original packaging. We bought it for £40, would accept £20. I can post the book to you for extra P&P charge.
We started the course with my husband this year, it was great as we could listen to CD's in the car or while cooking. We found course very practical and easy to understand. Will defo. continue next year.
We are selling the book because we bought two, one for each of us, but shared just the one at the end.
Thank you for looking.
