Catherine,

I hope you don't mind but I am going to clarify something here on your behalf.

To be part of a group of 7 that gets a free space thereby making the cost £170 each, all 7 people need to be paid up members of the DSC.

If you are not a paid up DSC member then the cost is £199.

The 7 for 6 deal is to paid up DSC members .....

Hope that helps.
