[Pile o' VR4]

You're missing the point. You CAN run on down to your local parts store to get a joint. No need to get one from a "vendor."

Also, there are varying qualities of joints out there. The one I purchased has a LIFETIME WARRANTY. I'm going to assume that the person you are referring to would normally retail for ~$21.49 and come with a 2-3 year warranty.

But alas, I cannot stop you from wasting money. I can get the very same part for $25-30 cheaper, locally and immediately and I'm telling you can too.
