Exactly. I recently bought a razer blade stealth through amazon, but the speakers were messed up and there was coil whine. I installed the recommended firmware upgrade but that caused Linux to crash with non-standard ACPI behavior. I decided to go through razer support because I know it's better for them. After over a week and maybe ten hours of emailing back and forth with support, I was asked to reinstall windows and see if that worked... Instead, I just clicked a few buttons on amazon and dropped the laptop off at the local UPS store and was done in ~20min. There's a reason Amazon is in its current position. If I had bought from the razer store directly, I would've had an even worse time.
