Newegg: No, We'll Totally Take Returns After You Install Linux
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 event, it's not helpful to provide disincentives for companies to own up to mistakes.
