restocking fee

I buy most of my computer, audio, video, & etc. from New Egg online company. I have never had a problem, that is till now. I ordered a very low end open box computer, when it arrived it was defective. I then checked how to return it for a refund. This is when I got the big surprize, a very big re-stalking fee plus the shipping back. I urge you to read the return polices of not only New Egg but any online or brick and mortor store.
A quote from New Egg, "Refunds are subject to a 15% restocking fee, which is deducted from the refund amount".
