Greggs Derby Biscuits Nutritional info needed (UK)

Options
Please please help!!

I have a weakness for Greggs Derby biscuits but cant find any nutritional information on them at all. They are not sold in all Greggs so am assuming it may be a regional thing, most probably the midlands!!

They are round shortbread type things but slightly more cakey with sultanas in and absolutely divine!!

Without a doubt the perfect combination of cake/biscuit in one! I could live off them but i wouldn't as i know it would be awful for my lower body (typical pear!).

Anyway to get to the point anyone have any ideas as to how many calories one of these may contain?? I am currently guestimating around 250-300cals!!! Any help greatly appreciated!!!

Thanks
Me =)
