Dude, you acted like a total moron before they even told you that they won't pay for you to ship to them. No wonder you received the response you did. And typically thats the way that most companies work. Not to mention that you bought the PSU 10 months ago and knew that there was a problem when you first bought it.
I received a 650w XXX Edition Semi-modular power supply last March from newegg, only to immediately find out that AFTER removing the shrink wrap, the box had already been opened by someone. I immediately took video of the knife slices in the packaging and the two stickers that had been removed that show you whether or not your product is brand new. Obviously since they had been removed my product is not brand new.
Worse yet, I later find out when going to send in my UPC code for the MIR, that there TWO new UPC code stickers slapped over the original UPC code printed on the box. AND there was at least one new sticker (that I can see for sure) over top the original serial number on the PSU itself. So basically I just received a used PSU that had been returned at least twice.
So instead of eating the $30 MIR to make sure you had a Brand new PSU you stayed with one you suspected was faulty to begin with. YOUR FAULT and you even admitted to it
I called Newegg to complain and they were willing to send out a new one and pay for shipping and all that, but I'd lose the $30 MIR. So I rolled the dice and kept it. BIG mistake.
Quit bad mouthing a company that has it policies in place that are typical of a majority of companies for your own screwup.
