Selling parts and lack of manners.

i have found that if you INCLUDE shipping costs IN THE PRICE , guess what ? it weeds out all shipping cost questions.
if someone wants to buy something from me , my shipping is ALWAYS included in the price. I generally give someone 24 hours , to give me an answer , then I move on, BUT I let them know , I am moving on. I have never had an issue selling one single thing with this method
