Since their site was full of knock-offs and half of it ships from China? Every time I shop on Amazon, I have to cross-reference with like 8 different sites to make sure I'm ordering the right thing and that the price is fair.
A good filter to start with is only products fulfilled by Amazon, and a step further, only Prime products. Granted, the due diligence still sucks, but I spend several thousands of dollars a year on Amazon products, and aside from the products that I know are cheap (like $4 phone cases) I've never had any issues.
