seller won't return my pm's

I have had great experiences buying and selling parts here
Although i have sold more than i have bought i just feel if your going to take someones money why not take the time out of your life and go ship the part a.s.a.p
I understand some people work hard and cant make it to the post office or shipping company right away thats fine maybe just state that to the buyer so they know it is going to take a few days or a week
I always say to my buddies that us mopar guys are are honest and stand up guys and gals
Lets keep it that way
