Hi i have made A3 and A2 a request option (in most listings) rather than including them in all of my listings to make space for new listings which will have both A2 and A4 to Start, this allows me to keep older listings active in the format that sells most (A4) but if you do want A3 or A4 just send the name and set number (001 to 050, 051 to 100 etc) and i will add the size back to the listing.
