For example, I'm shopping for landscape lighting right now. You can spend a lot on landscape lighting. A nice bronze spotlight from a "good" brand like Kichler can run you $100+ ea.[1], and I need 8–10 of them.
Conversely, I can get an 6-pack of albeit-plastic spotlights off Amazon from a Chinese company for 40 bucks, with 4.5 stars and 252 reviews.[2]
I am getting ripped off with Kichler? I am getting crap from Zuckeo? Who knows!?
