I have been searching around for the Michel Thomas French audio learning guides to use alongside my OU study, as they get superb reviews. The selling price for this particular course is between £38-£40 (from Amazon and Play).
The standard price on the The Book People is £22 (pretty good anyway) but I submitted the following promo codes at checkout:
VALENTINE20 - 10% off orders over £20 (valid until 14/02, taken from QUIDCO website)
ZD533 - free standard delivery (taken from TOPCASHBACK website)
possible quidco and topcashback of between 6-7%
unfortunately they do not have any other of the Michel Thomas courses, maybe in the future :-) I have used The Book People before (posted the deal about the Hummingbird Bakery cookbook - they are still selling it at £4.99!!) and they were brilliant.
I hope this helps someone!
