I recently had an experience where I specifically ordered a part from the US for fast shipping. Something like a week or two later there was no activity on the shipping label, turned out it was being shipped from China. I called customer support and was told they would give me a refund. So I bought a replacement under the assumption the refund would process. The part mysteriously showed up the next day even though the shipping label said it was still in china.

I eventually got my refund and returned the product to seller, but it took something like 4 hours of phone calls over 11 different calls and 3 weeks and threatening a charge back. I haven't shopped at newegg since then and have been using Amazon since. Not ideal but they are much more reasonable about returns.
