Blue Signed photo and CD

Due to the recent Blue reform, I think this may be a good time to invest in a piece of signed merchandise. Conveniently enough, a friend of mine would sell me theirs which is perfect!

It's quite a big photo frame containing a great looking photo of the 4 band members with the HMV puppy (At least i assume it is, there was a HMV logo in the background of the shoot) The photo is individually signed by all 4 members and a certificate of authenticity is on the back of the frame. It also includes a CD of their first single. She says she bought it originally for £115 and wants a respectable offer. I was wondering what do you think I should offer?! =s Many thanks in advance.
