One major caveat that I just recently discovered - purchases made through Amazon are only covered if they&#x27;re actually sold by Amazon, not through a third-party reseller and fulfilled by Amazon.<p>If you change your purchasing habits to choose items only sold by Amazon, you could quickly exceed any possible savings by paying the higher direct price than you&#x27;d pay for the same product (with the same shipping time) that you&#x27;d get from a third-party merchant.<p>Just an FYI if you&#x27;re thinking about signing up for the service.
