Not 100% sure on this, so mods, please correct me if Im wrong.
Look in your
pwnsettings.d2l
You should see this close to the top:
/* ææææææææææææææææææææææææææææ
ShopIt!
ææææææææææææææææææææææææææææ */
// ShopIton=true/false Set this to true to shop every npc you talk to, false to skip this
// AlwaysMalah=true/false Set this to true to shop Malah every run
// AlwaysLarzuk=true/false Set this to true to shop Larzuk every run
// MalahNotLarzuk=true/false Set this to true, and you won't visit Larzuk after going to Anya
// GoToAnya=true/false Set this to true to shop at Anya
ShopIton=false;
AlwaysMalah=false;
AlwaysLarzuk=false;
MalahNotLarzuk=false; //This is for use with Always Larzuk. See above
GoToAnya=false;
Follow those instructions, replace false with true to set it to your liking. I believe shop it will check your snagit file for items to look for. Just a half way educated guess.
