Update: according to the webpage, apparently ALL pre-ordered copies will be signed by the band, not just the first 100.
The first 100 people to pre-order Bottled at Source at Recordstore.co.uk will get a signed copy. Signed copies are strictly limited and will be sent out on a first come first served basis. One signed copy per household. To ensure you receive a signed copy order this CD separately any other titles.
It is currently unknown whether you receive confirmation whether your CD is signed or not. Also, there might have been 100 pre-orders already.
