This is an excellent offer that I saw in The Times today.
Half price (plus P&P) Michel Thomas language CDs.
For example, the 8-CD French, German, Spanish or Italian foundation course packs are £35 each + £2.50 P&P, normally £70.
These are excellent CDs (I've used the French ones already, and am now onto the German ones), but one tip: don't buy the 2-disc £10 Language Builder until you've at least gone through the 8-disc foundation course first. They're very good, but they throw a lot at you in a short time.
Excellent courses, certainly the best I've used, and I've never seen these CDs sold at this price before.
Mind you, I'm intrigued as to whether the new "EarWorms" way of learning is any good. These are available from Amazon.co.uk for about a tenner, and there are a few demos available here: http://www.earwormslearning.com/set_earwormslearning.php
Basically, it's like learning your language of choice by listening to a few phrases against a hip-hop/jazzy background music track.
Btw, I'm learning these languages as I'm off to live in Switzerland. There, you can buy an annual travel pass which lets you travel on all their incredibly clean & reliable trains, buses & trams all over the country at any time of the day or night, for just £25 a week. Now THAT's what I call a hot deal... I wonder if Virgin Trains / First Great Western will price match...? ;-)
