http://www.holidayhypermarket.co.uk/ are owned by tui but i am sure i have seen thomas cook holidays on here in the past.

I dont give much truck to these so called deals,
Walked past my local thos cook on Monday it had the managers specials in the window 3 star Corfu from Birmingham caught my eye at £289 each based on 4 shearing self catering, showed the OH, and her comments were "" thats expensive""
we are going the same week 3 star half board for 2 people for £265 each we booked in May [not i must add with either TC or Tui]

I don't think they have specific late deals website, they just have a section on their main website http://www.thomascook.com/lp/1z6-deals/

Check the 'Last Second Getaways' and 'Cheap Holidays' links towards the bottom of the page.

Also take a look at the 'Cheap Holiday Deals' tab on Direct Holidays http://www.directholidays.co.uk/

Yep just look on their website. They do have some cracking deals just outside of the school holiday season
