I've been watching videos on Shenzhen via Gamers Nexus YouTube channel. I reckon it's nice having everything tech-related in one physical locale, but the fact that it's custom to haggle over merch is enough to put me off. It's all just so hectic... >_<'
Seeing a few different videos of people going to China to directly get parts, it also seems like the Chinese often aren't too keen on selling to, let alone haggling, with foreigners.
I shall watch the tech Jesus video once I get out of bed~
