Instructions:I know there's not many Thomson Holiday codes around at the moment.
The code 185 should give an extra £40 off a summer 2007 booking i.e. departures upto and including 31st October 2007. (Minimum £550 spend).
Put code in promotional code box and click on validate and extra discount should be taken off.
If you went through 'deals' option at top of Thomson page, the code probably won't work. Make a note of the price, date, accom details etc. and do search again after clicking on 'holidays' at top of page: when you get to code box, insert code and it should work and give you extra discount.
