Oh I'm very happy with what they've sent this time. The papers aren't "used" by being cut into, or scribbled on like the previous ones, it's just that there are 3 of some papers but only 2 and 1 of others, as if there were originally 3 of each but some have been used.
I didn't complain the last time as it seems churlish to complain about something free. I did mention it as an aside when I had to complain about something else, and the response was just that it was a studio sample.
In your case as you had bought the goody bag and presumably it wasn't described as part-used, you did right to complain.
