As I read more DIY building threads, blogs, articles, ect..... I've noticed some recommend buying local to avoid the hassle of paying returns and restock fees that you can run into with online companies if you have a bad part? I was wondering what everyone here thinks of the situation? Is it worth paying 20 dollars more for my processor and another 20 more for my MoBo if it saves me that hassle of return shipping it and such? How common are bad parts?
