I'm 99% sure this is fake or that it wasn't UPS who delivered the package. I can see virtually the whole box in this image and it's clear that the package is in pretty decent condition and not covered in mystery stains.
While that was true a number of years ago, I don't think it is anymore. Amazon has their own shipping network. They've been working to replace UPS by shipping the packages themselves. At least that's how it was last time I worked with them.
And as others have said all my Amazon purchases are delivered directly by Amazon either in a white van or an Amazon branded delivery truck similar to a UPS truck.
Sheesh. There will be no other companies except Amazon, Google, Microsoft, and a few social media companies in 20 years. Amazon is even doing health insurance now.
Amazon definitely does contract out the to other carriers, depends on volume and where you live.
