This particular legal question should be a no-brainer, but one never knows. I'm rather appalled that Amazon continues to abuse its warehouse workers even after all the bad press they have received. That makes me feel better about not buying things from Amazon, since they now hit their customers with state sales tax.
Amazon, if any one of your products costs $0.01 more than any other retailer on the Internet, then I'm not buying from you, because morally you're just the same if not worse. There is zero loyalty to Amazon. I get a creepy feeling just thinking about the people that run Amazon. They have no morals, so what's to stop them from selling tainted or defective products, other than fear of punishment?
