There is already a thread running with promotion codes.

I've just tried to use this code and it says that the booking must be over £999 to validate it.

Yep you have got to spend £999 or more to qualify for the £100 off.

Hi! try : It-holiday . This prom code will get you £30 off a thomsons holiday, no matter how low the holiday price is, or when you book for. (Like someone else mentioned the bluebird code is for hols over £999.99, and is only valid on holidays taken until 31 April 2007). Regards, BBB.

I'll lock this topic as we already have a thread regarding codes. This will avoid duplication and keep all the information in onen place.
