These days I avoid Amazon where possible since so often it's just cheap Chinese knockoffs or obviously returned products sold as new.<p>B&H has been a godsend for tech, especially since there's no tax with their card. Crutchfield/Headphones.com has been great for speaker and audio gear. West Elm has a consistently premium quality for kitchen, home, and furniture items (though furniture is a story of its own, with even better vendors.) Walmart/Target/BestBuy have been good for everything else.<p>If you're too lazy to figure out yourself which products are quality, Wirecutter, NyMag, and Consumer Reports all perform unbiased testing of multiple products in almost every product segment I can think of.<p>And for simply next-level quality, nothing beats DIY. Personalize the final product exactly to your specifications, choosing the highest quality or even custom-machined parts with zero cost cutting. Requires time and passion, however.
