I've now set up the Big Book of Halloween Masks as a separate purchase. You can get them for just $9.99 here Printable Halloween Masks
You'll still get the Halloween masks if you purchase the Big Book of Animal Masks as it's still available to download in the members area. I just thought seeing as it's Halloween that people might just want the Halloween masks.
If you do just purchase the Big Book of Halloween Masks you'll still get access to the members area where all the extra masks are (11 Halloween and 18 animal masks to date), so it's a proper bargain 79 printable masks for $9.99!
