It's a remarkable (to me) number of comments to the OP saying they're glad Newegg refunded the money and apologized, but they would still never buy from them. Seems to me like Newegg acted quickly and unambiguously. The flip side of the "punish bad behaviour" coin is "reward correct behaviour". Maybe it was, as many commenters are suggesting, just the public shaming that got Newegg to act, but maybe not... in any eve…
If the refund was a one-off situation to quiet the public outcry, and they don't care about fixing their general problem, then why would I purchase something from a company that I lack confidence in?
I regularly buy things from Amazon even if it's a little bit more expensive because I've been using them since their inception, and I have 100% complete confidence in them.
