I recently bought an item from Newegg.com that had a $15 rebate associated with it. I could not get the rebate processed online. I sent emails to Newegg and they responded to each request in a timely manner. After a few attempts to fix the problem, Newegg provided a $15 refund on the item. I think that this was good customer service. It was not pleasant trying to follow the rebate instructions and getting rejected each time but in the end Newegg did the right thing.
I've never had a bad transaction with this company. Since I live in NYC I always get my packages delivered in one or two days without paying for expedited shipping. I like that
