I'm not sure what your situation is, but I did an intensive 2 week course at the American Institute of Stuttering in NYC and it really helped me break down some of those initial hurdles. You might want to look into Cognitive Behavioral Therapy as well - it's some interesting stuff. As a stutterer we really are our own worst enemies. Getting your mind and emotions right is key. You might just want to set a goal for yourself to call 3 stores a week and just ask if they have X product in stock. Little steps, but you can do this. You really can change your life - I'm proof.
