Raine,
Erm.. I'm nt very sure le.. cos that time we went to collect..
Yes.. they corespond by email of all the changes and over phone too.. ;p
Cos when I reached hm.. look at the sample copy realised there's a few more changes, I call them, they change. Then the next day when I wake up and look at it again.. and found other minor mistakes.. then I called them again.. and make the changes.. then they make the changes and send the amended sample copy by email.. in total I change at least 5 or 6 times.. but no complains from them.. and yet they oways end with.. do free to call us back if any more changes is needed.. =)
I tink they r nice n helpful lo.. ;p
