Have been a customer of Newegg.com for almost 19 years. Recently tried to return an AMD Ryzen 5800X3D CPU that failed after only 4 months. Discovered to my horror that it was not for sale in the United States and I couldn't return it to AMD -- no warranty!Newegg and seller Senytech flat out refused to explain the problem and said only that they have a 30 day return police.
