Yes I refuse to pay five times the amount of the other volumes, especially when I have the paperbacks already. It is frustrating however to have an incomplete set when the rest of the set came to $1980, making it perhaps my biggest TF investment (even more than my two Unicron's combined!) not counting the Transformatorium Shed itself.
I will be shooting off at least one or two more emails in a month, though admittedly the likelihood of success is minimal. If people wish to join in a group email - all good. If not, no dramas.
