If I may just add something, Mr. Chair, to the answer to Mr. Butt's question, again, in the MAS section on the large-volume mailing, it says:
Fully assembled (including sealed) printed materials prepared in whole or in part in Members' offices or by an external supplier may be mailed under the conditions outlined above. It is the Member’s responsibility to ensure that these materials comply with the By-laws and policies of the Board of Internal Economy.
