No it doesn't. However, I can be very persuasive. An anonymous on-line seller can duck and dodge. A retailer can't run away.That doesn't mean you're going to get the satisfaction you want. I've done a lot better dealing with sellers on Ebay than I have local dealers. Just my personal experience. YMMV
I am batting 1.000 when it comes to returning defective or non-usable merchandise. That settles it for me.
Call me cynical but quite frankly, I have read far too many horror stories about on-line purchasing venues like ebay which have reduced my trust factor to about nil.
